Disappointment Cleaver Route Update -- July 20th

The new route variation (blue) on the Emmons Shoulder.
As the freezing level continues to stay near or above 14,500 feet, the glaciers on Mount Rainier continue to change as well.  Guides recently put in a new variation that directs climbers up towards the "Emmons Shoulder" from the top of the Disappointment Cleaver.  All of the wands and pickets placed on the older variation of the route have been pulled.  If you choose to climb the older route be prepared to navigate with a GPS, and protect the steeper headwall terrain and major crevasse crossings. 

The new option avoids the major ice fall zone that occurred on the Ingraham Glacier a couple of weeks ago, but doesn't eliminate all of the overhead hazard.  There is still potential for ice fall onthe new variation.  Keep an eye out for looming ice cliffs above and don't linger or take breaks below these hazards.

Rockfall near Cathedral Gap has also been active at all hours (including in the middle of the night) due to the warmer temperatures.  As climbers finish crossing the Cowlitz Glacier and gain the rocks at Cathedral Gap, the transition from glacier-travel mode to rock-travel mode stalls them directly beneath the hazard.  Prepare your team ahead of time for this roped transition; make necessary rope adjustments out of the rockfall hazard zone and pass through quickly.  It's also worth taking a break, getting a snack and a sip of water, before crossing the hazardous area so that everyone can move their fastest if needed.

Overall, the Disappointment Cleaver route seems to be in late-July conditions. It will continue to break apart and become more circuitous as the summer goes on.  The high pressure and sunny skies that settled in a little over a week ago remains in place and has made for great weather conditions on everyone's summit day.  And, lastly, it's still the busiest time on the mountain; consider climbing during the weekdays through the rest of July and early-August to avoid the crowds.

Inter Glacier and Emmons Conditions - July 17th, 2018

Here are some pictures of current conditions.  The best route up the Emmons Glacier, and the one being used most frequently over the past few days, is still ascending up and climbers' left of the "Corridor" through the "Garbage Disposal" before traversing right at around 13,000 ft to tie-in with the older boot track.  More information on this route is here: 

While the "Garbage Disposal" avoids many crevasses, it is steeper and subject to icefall.  Be sure to ask if this overhead risk is worth it for your team and consider how long you will be exposed.  Additionally, there are many crevasses opening up right out of Camp Schurman and near Emmons Flats.  The Corridor is also quite crevassed and there was a report of at least one team member experiencing a roped crevasse fall on Monday morning.  If attempting this route in its current condition be prepared for route finding and crevasse rescue.  It is in late-season condition.

The Inter Glacier is also entering late-season condition and features crevasses along the bootpath which are difficult to see until you are right next to them.  Glissading is not advised and roping up is not a bad idea.

Emmons Update - July 15th: Warmer Temps Taking a Toll

First morning of wildfire smoke this season.
It seems that the high pressure of summer has finally arrived and with it so have the climbers and rapidly changing route conditions. Throughout the weekend, nearly all camps were booked with climbers: from Camp Schurman and the Emmons Flats, to Camp Curtis and the Inter Glacier bivies. As we continue to roll through July & August peak season here at Mt. Rainier, climbers should show up with some flexibility to their plan and perhaps a backup option or two. That being said, many groups were up on the mountain this weekend and a few teams had successful summit attempts despite heat and somewhat deteriorating conditions of the route.

Approach route onto the Emmons from Camp Curtis continue
to melt out rapidly with high temps this week.
With a rapidly depleting snowpack all over the mountain, the Inter Glacier and the approach route off the Camp Curtis ridge and onto the Emmons is melting out quickly. As of yesterday, climbers are now avoiding the obvious line in the photo and are dropping in/exiting the Emmons slightly downhill in order to avoid the steeper, slabby and exposed rock scramble. Rangers have been happy to see that nearly all parties are roped up as they come into camp. Perhaps it's only due to the more broken nature of the Emmons this year, but that section of glacier is heavily crevassed and certainly warrants the deployment of ropes, harnesses, helmets, axes and crampons (full glacial mode). Once in camp, climbers can expect to share space with many other eager climbers so camp etiquette and hygiene are paramount.

Full camps are a theme throughout July/August peak season.

 In terms of route conditions, the steadiness/reliability that we saw on the Emmons throughout much of the early season has finally begun to deteriorate. Arriving in camp on Friday, rangers received reports from both guides and climbers alike of a hollow route from top to bottom that was difficult to protect. Reports of large, sagging, "team eating" bridges, postholling into blackness and unnerving, soft snow conditions gave rangers enough reason to try to find an alternate route up the mountain.

between 11,400' and 12,600'.

 Although rangers were able to climb via a different route between 11,400' (top of the corridor) and 13,600', the steepness and exposure of the upper pitches didn't make it an ideal alternative to the current bootpack. That being said, a variation to traverse back into the main boot pack around 12,600' still cut out nearly 1,200' of the most hollow section of track. As of Sunday morning, there was a mixed-bag of attitudes in high camp. Many parties decided that the warm temperatures and objective hazard was simply too high-risk and stayed in camp. Some parties attempted the old boot pack today and all of them turned around due to the sketchiness of the crevasses all around. Finally, a few more experienced parties were willing to attempt the new re-route and some of them had success to the top. Most folks that have been able to summit have been topping out by sunrise and returning to camp by 9 or 10 am to beat the heat.

red line is the old, most hollow section of the route.


Topo of the new re-route. Cutting out the old bootpack (in red) avoids a large section
of hollow terrain between 11,400' and 12,600'.

No matter what choice you make if deciding to climb the Emmons, rangers are stressing the importance of personal risk assessment and risk management amongst groups as they show up in camp. As of now, the route is no longer the "cruiser,"  stable route that we often expect earlier in the year. For parties with solid mountaineering experience, including excellent comprehension of crevasse rescue, running belay/anchor belay and glacial navigation techniques, the Emmons might be a great challange under the current conditions. For parties with minimal mountaineering experience and less confidence in unstable glacial conditions, the current Emmons route might offer too much hazard/risk. Even with a new re-route there is still a lot of uncertainty/risk from the first crevasses encountered out of camp all the way to the nearly 75' overhung bergschrund curtain that the route passes directly over at 13,600'. Successful and safe passage up the current route will require a full repertoire of skills from belay techniques, route finding (it will undoubtedly change daily as things continue to melt out this week), fitness and the ability to ascend and descend by early morning.

Disappointment Cleaver Update -- July 12

Looking down the icefall debris on the Disappointment Cleaver route. Note climbers for scale.

The path of the Disappointment Cleaver route remains largely unchanged over the past few weeks.  The route still climbs up and left from the cleaver to the top of Gibraltar Rock before continuing up to the crater rim. This may change as guides work to re-route the path in coming days and weeks to reduce exposure to serac hazards and as the crevasse crossings along the route widen.

Looking across the Ingraham Glacier toward Camp Comfort. Note icefall debris and leaning seracs.

Crossing the icefall debris.
The biggest concern this week has been objective danger from serac fall on the route coming from the upper Ingraham Glacier. There have been two very sizeable ice falls starting at around 13,000 feet, resulting in a debris field that is a few hundred feet wide and roughly 1000 feet long.  Many parties are choosing to not subject themselves to this hazard by stopping their climb atop the cleaver at 12,500 feet and deciding to come back another time.  If you choose to climb through this section, move quickly and DO NOT STOP until well away from any overhead hazard.

Rockfall below Cathedral Gap.
With warming temperatures, the large rockfall debris near Cathedral Gap is becoming increasingly dangerous as the snow pedestals holding boulders begin to melt out. Above freezing temperatures at night mean that these behemoths may fall at any time of day. Move swiftly through this area.

Ladder at High Crack.
 A pair of short ladders were installed on the route this week, across widening crevasses. If you feel the ‘need’ to jump across a crevasse, look for an alternate route. There is no reason to take flight during glacier travel, contrary to what many books and social media posts may portray. Ankles and knees rarely take the hard landing well and many injuries result from being airborne - especially when wearing crampons. 

Be sure to practice Leave No Trace while on the mountain. Blue bags can be obtained at the ranger station when you get your permit; use these any time you are not at a bathroom. The bags can be deposited in labeled barrels at Camp Muir and in Paradise (not in the toilets). Do not leave your human waste along the climbing route for others to see or clean up!

July crowds to the right and icefall debris to the left.
It’s shaping up to be another busy July weekend on the mountain. Plan ahead to obtain your climbing permit (even for single-push attempts), be courteous to other climbers, and make good decisions for yourself and your team.

Kautz Route Update

Rangers climbed the Kautz Glacier route this week and were pleased to find pleasant climbing conditions. The Kautz route is more technical than both the Emmons and DC, however, it remains a good stepping stone for those contemplating more challenging objectives on Rainier.  The route requires a higher level of technical skills in order to negotiate the rock step, technical ice chute, and glacier route finding. Rangers ascended from Paradise to Glacier Vista, then descended toward the Nisqually Glacier.  This approach was still mostly snow covered. 

The route taken on 7/10 to a bivy site near the Turtle Snowfield.

There are two common ways across the Nisqually; one heads toward the "Fan" and the other traverses a little higher towards the Wilson Glacier "Gully" just above. Rangers opted for the Gully approach as the Fan is quite melted out and the crevasses on the Nisqually Glacier crossing didn't prohibit access to the upper ridge. Remember to rope up for these glacier crossings, and take a GPS track once you leave the trail in case clouds roll in and visibility deteriorates during the climb.

The Wilson Gully approach from the Nisqually Glacier.

Above the Wilson Gully, rangers ascended the lower Wapowety Cleaver to The Castle at 9600 feet.  Many good campsites exist in this area between 9,400 and 9,800 feet, in the vicinity of The Castle. Other bivy sites can be found near the top of the Turtle Snowfield around 10,800 feet. Rangers found running water near both The Castle and the 10,800 bivy site.  

Shortly after departing camp the next morning, rangers arrived at the rock step.  Currently, a 25' rappel is necessary to negotiate the rock step and access the Kautz's ice chute.  Old, tattered fixed ropes mark the top of the rock step.  As with all fixed equipment, the fixed lines should be inspected for core shots or damage before use. Be prepared to back up any gear you encounter and use your own ropes/equipment if you doubt the quality of fixed gear. The ice chute is sun cupped from top to bottom.  The snow pinnacles offer good security, but don't hesitate to utilize running belays or pitch out the terrain. Decent alpine ice can be found near the top of the chute to the left or right of the gut.

Looking down the Kautz ice chute.

From the top of the chute, meandering glacier travel brings you to the Wapowety Cleaver at 13,000 feet. There are a couple small exposed bivy sites on the Wapowety Cleaver, but no running water.  From the Wapowety Cleaver, a few long switchbacks bring climbers across the upper Nisqually Glacier to the crater rim.  The upper glacier is in good condition and smooth. A few large crevasses in this section have thin snow bridges, and it may be a good idea to belay your partners across these crevasses.

The route taken to the top from high high camp on 7/11/18
If you're planning a climb on the Kautz, grab some blue bags from the ranger station at Paradise or Longmire when you get your climbing permit. Wherever you decide to bivy, be sure to keep camp clean and pack out any trash you find.

DC Update: Objective hazards become palpable

Ice fall debris with Gibraltar rock in the distance. Photo: Tyler Jones 

This morning guides reported seeing debris from a large ice fall on the upper mountain.  The large ice block tumbled in the middle of the night when no parties were on the route. The event occurred at approximately 12,600 feet on the Ingraham Glacier, just above the top of Disappointment Cleaver. Ice blocks tumbled over the climbing route and continued down the glacier at least another 1,000 vertical feet; simply put, this would have been an unsurvivable event.  The route through this area will be more difficult (and slower) to travel across with the new debris and uneven footing.

Events like this are a good reminder of why it is important to be aware of the objective hazards on the route, and to minimize your exposure to them. Move quickly through zones that are underneath seracs (and rockfall), and keep your senses tuned for the sound of tumbling ice blocks. More seracs in this same area could fall in the future as the glacier continues to move downhill.  It is impossible to predict when this might happen. Any serac that is tilted downhill and disconnected on the uphill side could tumble at any time. Have a discussion with your team members about your strategies for moving though areas subject to ice fall and don't linger in these areas.

The rest of the DC route remains unchanged.  We have entered peak climbing season in the Muir corridor, and the route will tend to be crowded on weekends.  Remember to stay courteous and friendly with other climbers you encounter on route, and keep the mountain clean!

Emmons-Winthrop Route Update

Climbing Rangers ascended the Emmons-Winthrop on July 7th and were surprised to find that the route remains very direct, but is trending toward late season conditions. The route was only 2.5 miles long from Camp Schurman to the summit, zig-zagging through a jumble of cracks directly above the Corridor before angling up and right above a giant rectangular serac.  That being said, this could change at any point, and expect it to with the really high freezing levels that are coming in this week.

Giant rectangular serac illuminated by the sun.

The points we took away from our climb and want to spread to other climbers:

1. Crevasse fall potential is high. Use protection on larger crossings, especially if the slope is steep and a fall could drag your partners into the crevasse too. When temps are so high, get up and down early. When crossing something big, how can you get back below it if that bridge collapses while you are above?  Keep a look out for alternative routes.  

There were a couple of large bridges we crossed (around 13,100' and 13,500') that had steep headwalls on the uphill side.  Arresting a fall on the steep headwall if the lower person broke through would be impossible.  Place a picket on the uphill side of the crevasse after the leader crosses to have it between rope-team members (running protection). In the warmer temperatures that are coming, consider a full belay for crossing the larger bridges.  

Steep headwall above a hidden crevasse.  It's hard to assess how thick and strong the snow covering the crevasse really is.

2. Take a GPS track on the way up. If you climbed the DC before and expect to find the Emmons Winthrop as easy to follow and straight forward, you will be very disappointed and ill prepared. This is not a maintained route. Don't expect the bootpack to be easy to follow or to always go the best way. Don't blindly follow tracks across areas that you are not comfortable crossing. And if clouds roll in, finding your own way down can be nearly impossible in a whiteout. Have a GPS, download the maps for Mount Rainier, and know how to use it.

3. Stick with your climbing partners. Again, STICK TOGETHER.  As climbing partners, it's your duty to look out for each other. If one person is feeling run down or showing signs of AMS, you should all turn around together. Don't leave your buddy sitting on a glaciated slope while you "quickly" tag the summit. As you head down from Schurman, it's good to keep your partners within visual distance, at least to Glacier Basin. People have fallen in the cracks on the Inter Glacier and if no one witnesses a fall, it can be hours before help could arrive.
Large Crevasses right above and below Camp Schurman
4. Be courteous to other climbing groups. The mountain is always busy in July. The camping and climbing use quotas (read: limits) for the standard routes are filling up fast. This means a lot of climbers on the routes. At some point you will pass every group on the route and remember, if you are feeling 'hangry' or tired, and sore, they are probably feeling just as bad as you. And everyone's day can be a lot safer and smoother if you just communicate with other groups (Are you crossing a crevasse now? Heading up or down? Taking a break in a safe zone, out of the way of other parties?).  And maybe even try to share a smile with folks.

5. Know your own limits (and your group's) and stick to them. Stay well within your abilities.  Don't get summit fever. If you come across a crossing you are not comfortable with and don't see an alternative, don't do it. The route is getting toward late-season conditions and requires increasing amounts of experience and skill to navigate. You can always come back another season with more experience and knowledge under your belt.

Be safe out there and have a fun climb.

Kautz Glacier and Liberty Ridge In-Depth Route Guides

Based on the success of the two route guides that were published last year on the Disappointment Cleaver and Emmons-Winthrop Glacier routes, we decided to publish two additional documents this year.  The two routes we chose were the two next most popular routes; the Kautz Glacier and Liberty Ridge.

Each route guide is 20 to 30 pages in length.  Similarly organized, each document gives overall statistics, climbing history, recommended skills, a physical description of the approach, ascent, and descent, how to get current conditions, weather data and forecasting resources, ski mountaineering considerations, risk management strategies, resource protection, search and rescue statistics, as well as many other topics of discussion relative to each route.

Written by Mount Rainier climbing rangers, the text of each document is a holistic body of knowledge from nearly 1000 ascents of the 13 current rangers.  With the rough edges of opinions and approaches rounded out, the advice contained in the guides delivers the core elements of what you need to know.

There's something in these documents that you'll find interesting no matter what your skill level.  From historical use statistics to search and rescue data, you'll likely learn something you don't know.  The document contains weather forecasting recommendations and data, recommended additional reading, and lessons learned from search and rescue incidents.

Here are the direct links to each document on Mount Rainier's official webpage:
Enjoy the documents and have a great ascent!

Busy Weekend = Full Camps

Hey everyone,

We figured this was going to be a busy weekend!

The high camps have filled up for Friday and Saturday nights already.  Here's how it breaks down:

There are 110 people allowed at Camp Muir each night.  There are 48 people allowed at Camp Schurman.

Camp Muir & the Muir Corridor

Currently, Camp Muir is FULL Friday, July 7th, and Saturday night, July 8th.  Even for walk-up permits.  The only chance of getting a permit is if someone comes down early from their climb and checks out at the desk so that we can avail the numbers in the system.  Don't count on it.

Common overflow areas for Camp Muir are the Muir Snowfield and Ingraham Flats.  There are 36 people allowed at each of those spots.  Right now the system showabout 5 open spots for those areas.  You could conceivably walk up today or tomorrow and get one of those spots, however, this does make the climb longer from the Muir Snowfield (below 9,700').  And it is more difficult to go all the way from Paradise to Ingraham Flats in a day.  That's a long way.

Camp Schurman, the Inter Glacier, and Emmons Flats

Camp Schurman still has 15 or so spaces for Friday, but Saturday night is completely full.  Sunday looks better at this point.  Emmons Flats already has 15-20 folks both Saturday and Sunday night.

If you really want to climb Mt. Rainier this weekend, Camp Schurman is going to be your best bet, and you want to get to White River to register first thing.

I'm sure that will change by the end of 07/06 (today).

Single Push Climbers
Often climbers seeking to avoid camping restrictions try to climb the mountain in a 'single push.'  Single push climbers count toward the tally of total climbers on the route, even though they are not setting up camp. As such, single push permits WILL NOT be issued if the high camps are full.

Resource Protection and Visitor Safety

The current limits on campers at each camp each night has been in place for a few decades.  These numbers represent the maximum limit of people that each area can handle with regards to resource protection and visitor safety.  For example at Camp Muir, when we have more than 110 people camping, the number of climbers on the route gets so large that it becomes unsafe.  Rockfall from climbers above, long wait times at pinch points or technical crossings or ascents become untenable, as well as lines for the bathrooms (and managing the human waste collection systems) can all reach emergent conditions.

To ensure and satiate your desire to plan, we recommend that you submit a reservation.  Roughly 60% of the total of each zone or camp can be reserved.  40% are reserved for walk-up permits.


To make a reservation for the coming weeks, please visit the following site.  We recommend this every weekend from here on out.

“K” Spire Trip Report July 4th, 2018

Climbers approaching K Spire from Meany Crest via the Frying Pan Glacier

Earlier this week, rangers had the rare opportunity to head into the backcountry for a patrol that entailed rock shoes and cams rather than double boots and ice tools. With relatively limited intel on the quality of rock or route descriptions, it made for an enjoyable climb that felt a bit more "wild" than the likes of the standard routes on Rainier. Similar to the Little T approach across the Frying Pan, climbers found the glacier to be in good shape which made for easy navigating towards the spire.

Upon reaching the base of the ridge, the lack of climbers trails or bivy sites reaffirmed the limited traffic this spire receives. A quick climb up the talus gains you the ridgeline just to the west of the spire. Upon closer inspection, it became clear that the NW corner and North Face of the spire are flaky, exfoliating and of poor quality. Additionally, the rock on the South Face seemed to improve dramatically the higher you got up the face. Although rangers climbed the South face via a 3rd class ramp that put you into the better rock, a few other routes could easily be climbed depending on your willingness to deal with poor rock down low. A blocky dihedral system on the SE corner seemed like a viable option after pushing through 20 ft. of rotten rock. Additionally, there were a few variations from the top of the 3rd class ramp that might go between 5.7 and 5.11. 

After scrambling up the ramp, climbers roped up and began working up and right through broken blocks, slab, a high step (5.9) and eventually into a short chimney section that gained you access to the summit ridge. As stated, there were many possible variations but the route taken seemed to offer the best mix of solid rock and moderate climbing. Climbers were treated to a nice view up the Emmons glacier and across to Mt. Ruth. A quick look around made it clear that the best rappel line from the top existed off a large horn, directly above the 3rd class ramp.  A single rappel down to the ramp made for a clean rope pull and an easy stance to swap shoes and downclimb back to the ridge. 1 rappel to the ramp with plenty of rope to spare made a 60m rope seem excessive. A 50m rope might be the perfect length to get up/down the spire without carrying extra rope. 

Protection on the upper face was quality and took a handful of cams and nuts. A single rack from small finger sized TCU's to #1 including small-medium nuts is recommended for the route climbed. The harder variation may need another small piece or two. Climbing shoes were helpful but the route could have been put up in approach shoes with easier, mountain boot variations for the ultralight climbers. 

All in all, K Spire offers an alpine climb of a different variety compared to most within the park boundaries and is highly recommended for those willing to make the trek. Fun climbing and an impressive stance above the Emmons glacier make it a worth while venture. Despite the quality rock on the upper wall, climbers shouldn't overlook the hazard of the rotten rock lower down on the spire. Great care should be taken to ensure that holds, protection, ropes and partners are in secure locations to avoid dislodging one of the many death blocks perched on this rarely climbed feature.

DC Update - 7/4/2018

The Disappointment Cleaver route is basically unchanged from the last post on 6/28.  It still swings climbers' left from the top of the Cleaver towards Camp Comfort near the top of Gibralter Rock before switch-backing to the crater rim.  Thanks to the hard work of the guide services, the path is generally smooth and low-angled; pretty easy walking.  The Cleaver itself is still about half rock (lower) and half snow (upper).  Remember that you need to shorten your rope intervals while on the Cleaver so that your party isn't dragging the rope through the rocks and knocking things loose.

Looking up at the route from just above "Dunn's Roll."

The DC route contains several areas with the objective hazard of rock and ice-fall.  Climbers attempting Mt. Rainier should be able to identify such areas and move swiftly through them to minimize the risk of injury.  Here are some of the notable areas along the route with such hazards, in ascending order:

(1) Gaining Cathedral Gap from the Cowlitz Glacier.  There was a significant rockfall event in this area in May, and there are currently several large boulders perched on snow pedestals right above the climber path.  These will fall this season as the snow under them melts out.  Move quickly through this area.
(2) "Dunn's Roll" is on the Ingraham side of Cathedral Gap.  There is rock and ice-fall hazard here.  Additionally, there is slab avalanche hazard here in the early season or after fresh snow.  It is a terrain trap.  Move quickly through this area and don't stop until you reach Ingraham Flats.
 (3) "The Ice Box."  This is the area immediately above Ingraham Flats as you traverse climbers' right below an active icefall to gain the Disappointment Cleaver.  This is the the site of the worst mountaineering accident in North American history.  On June 20,1981, a large ice avalanche broke loose and buried and killed 11 climbers here.  Rangers and guides frequently observe independent parties stopping and even taking breaks among the ice rubble in this section.  Do not stop until you get to "The Backboard" at the toe of the Cleaver where there is a rock alcove that protects from rockfall.  This is a great spot to stop and take a moment to prepare to ascend the Cleaver ( i.e, shorten rope-lengths between climbers).
(4) The Cleaver itself is prone to spontaneous and climber-induced rockfall.  Pay attention to where you are in relation to other climbers and try not to climb directly under other parties.  If you are above another party, take care not to knock rocks loose on them and consider waiting for them to move out of the way.  Keeping your rope short so it's not touching the ground will help prevent rockfall.
(5) Seracs.  The route above the Cleaver changes throughout the season and year to year, but there are usually sections where the climbers' path crosses under seracs (large towers of ice).  Seracs can collapse at any moment.  Recognize where the route crosses under seracs and serac run-out zones and move quickly through these zones.
(6) Other climbers!  The DC is the busiest route on Mount Rainier.  You most likely will be sharing the route with several other independent climbing parties as well as guided parties.  Be aware that other people present a hazard:  They can cause rock and ice-fall.  A falling rope team can floss other teams off of the route.  Try to avoid being directly underneath another party in areas with rockfall or unprotected falling hazard.   Also, understand that there are safe and unsafe places to pass other people on the route.  Use good judgment and communicate with others.

A busy 4th of July on the DC.  

As you can see, the DC has quite a bit of objective hazard, particularly involving rock and ice-fall.  It is the responsibility of climbers to accept or deny a certain amount of risk, and know how to recognize and move efficiently through these areas to mitigate their exposure to those risks.  Climb safely.

Upper Mountain Human Waste Etiquette

This photo is a great example of what not to do when defecating on Mount Rainier.  Notice both
the proximity to the climbers trail, as well as Camp Muir in the background.  Next, notice the
Climbing Ranger picking up after this climber.  We don't especially enjoy doing this, so please
use a blue bag and pack out your own human waste.

It usually comes at the most inopportune time, but there are a few elements related to managing human waste that we want to cover in this blog post.

First, the Paradise Wilderness Information Center issues blue bags free of charge for climbers.  Please take a couple with you when you climb and plan to use them.  They're very lightweight and won't weigh you down much at all.

The next step is to use the restroom facilities at Camp Muir or Camp Schurman.  Remember, Proper Prior Planning Prevents "Poor" Performance.

When the time comes and no facilities are available, remove your blue bag from your backpack, step a ways off the climbers trail, and do your duty.  Please do your best to leave a clean area when you are finished.

Both of these photos are great examples of the wrong way of managing your human waste.  Remember, there are thousands of climbers who climb Mount Rainier every year.  Please do your best to keep the mountain clean, especially areas near the trail, camps, and the summit crater. Nobody enjoys seeing or walking over piles of human waste.
