Ptarmagin Ridge 6/19/25

Multiple parties have made attempts on Ptarmigan Ridge over the past few weeks with only one successful climb. Photos taken on 6/19/25 show an overview of the area and current snow and ice coverage on the route. 

These photographs were taken by an independent party of 3 that opted not to climb due to the current conditions on the route

Emmons Update 6/18

 

The Emmons Winthrop route is still in good shape and has seen many successful ascents and descents in the past week. 

The trail to glacier basin is mostly snow free with a few patches of stubborn snow the final mile before. Above glacier basin there are various boot packs up the inter glacier to Camp Curtis. The Inter Glacier still has decent snow coverage from the winter with on fern ice on 6/18. There are a few open moats around the various nunataks, but no open crevasses were observed.

A route to the Summit on 6/14/25

Although there is a well-established boot pack on a majority of the route climbers are encouraged to evaluate changing conditions and deteriorating snow bridges and make their own decisions on the best/safest path when necessary. There are a few points on the route where the well-trodden "path" crosses a marginal snow bridge. Safer crossings can be found by looking around to a less traveled area where a more robust bridge can be utilized or a crevasse can be end run. 

Crevasses at 11,400' - 6/14/2025


This last weekend we saw many descents by skiers and split boarders. When we talked with these parties on the route and back at Schurman many skiers used terms such as "bad skiing", "rugged", and "highly variable" when describing their descent. Many also reported carrying their equipment back down the mountain a distance before reaching a point they wanted to ski/board from. Further, rangers repeatedly observed riders get off their intended descent route at ~12,000ft landing them well above the corridor in broken and crevassed terrain. 

Boot pack at 13,400 - 6/14/2025

Overview of the Emmons route from Camp Schurman - 6/14/2025

If you are planning for a ski/board descent of the Emmons come prepared for variable surface conditions consisting of, sun cups, Penitentes, ice, and Sastrugi. If you are expecting planer surfaces and good corn skiing on the upper mountain you may be disappointed and find yourself in more challenging conditions. Carful route-finding is even more paramount when descending on skis due to the faster speed at which riders encounter terrain and a lack or rope to arrest a fall. 

If your team is planning on un-roping and riding down the mountain be thinking about your rope strategy... If you only have one rope for the team and the person who is carrying the rope falls into a crevasse, what is your plan??

North Side Photos and Route Info

The north side of Rainier 6/17/25


Climbing traffic has slowed down on the north side routes of Rainier over the last week due to changing route conditions and difficulty accessing some routes.

Liberty Ridge: Climbers have reported bailing from the approach to Liberty Ridge in recent days after having difficulty accessing the ridge from the Carbon glacier. Parties have reported a lack of adequate snow coverage on Liberty Ridge, which is typical for late June. Navigating the upper Carbon glacier has been difficult as well, with numerous open crevasses, necessitating circuitous travel.

Ptarmigan Ridge: Parties were successful on Ptarmigan in early June. There have been no reports of successful summits on this route over the last two weeks. Note that Ptarmigan ridge must be accessed from the White River campground this year due to the Mowich lake road closure.

Disappointment Cleaver 06/14/2025

Overview

With the summer solstice fast approaching, climbers have been experiencing long days and ample sunshine as many ascend the Disappointment Cleaver Route. We’re in a transitional period between spring and summer weather and snow conditions with changes occurring at every elevation on the mountain, from the lower slopes of Paradise to the summit. 

A low-pressure system will move into the region over the next few days, bringing the potential for significant wind, precipitation, dropping temperatures, poor visibility, and obscured hazards.  Always be prepared for wintery conditions, even on a daytrip up the Muir snowfield. The main hazards associated with this time of year include:

  • Rapidly changing and unpredictable weather, including whiteout and wintery conditions

  • Overhead hazard from rock and serac fall

  • Thin snow bridges over crevasses

Disappointment Cleaver (DC) Route

Some notes about the approach to Camp Muir:

On the way up from Paradise, please stick to the Summer Trail if it’s melted out and snow if there is no obvious dirt/rock trail. There are occasional markers on the lower snow "trails" beneath Panorama Point to indicate the Summer Trail. Please avoid trampling the fragile alpine wildflowers and other vegetation. 

There is water flowing from Pebble Creek above Panorama Point and we recommend filtering it if you plan to drink it.

Be ready to navigate the Muir Snowfield in whiteout conditions.

Above Camp Muir:

The National Park Service does not maintain the route; however, local guiding services do significant route-work and keep it well-marked with reflective wands. There is rock and serac fall debris scattered throughout the beginning of the climb above Camp Muir, most notably throughout the Ingraham Flats (see earlier posts about 5/19 Serac Fall) and the "Bowling Alley". Attempting to pass rope teams in these zones will not likely save time and instead it can cause tangled ropes amongst the massive ice blocks in the Flats. There are several crevasses to navigate leading up to the DC so plan rope lengths and teams accordingly. This is one of the many places to move swiftly on the route to mitigate the risks of overhead hazard.

Looking back on the Ingraham Glacier from the base of the Disappointment Cleaver. The “Bowling Alley” and debris from the 5/19 Serac Fall can be seen.


The DC itself is fully melted out and it primarily involves rock travel. Remember to use careful footing and don’t let your rope drag on the ground through this section; avoid sweeping rocks down on parties beneath you. The uphill party is responsible for mitigating this avoidable rockfall hazard. If you’re concerned about kicking rocks down on other parties, simply stop moving and wait for the area below you to be clear of people before you continue. Communicate and be patient.

There are currently no ladders on the route. There is a fixed-line (to be used for balance only, do not fully weight it) and several snow pickets that are maintained by the guides–use your discretion with this gear and please don’t remove any carabiners or equipment. There are complex crevasses and snow bridges to navigate above the cleaver, especially on the steeper transitions in slope angle. With warming afternoon temperatures, be observant on the descent for any snow-bridge sagging or significant changes in route conditions. Skiing on the upper DC route would be quite bad due to surface conditions (penitentes), and a fall would be consequential because of the major crevasse crossings and exposure. 

In such a dynamic environment, give yourself a large margin for error with the incoming weather system. Track conditions and stay flexible if you’re planning to climb the mountain to celebrate the longest day of the year. Thanks for reading and remember to thank the guides for all of the hard work they do on the route!

Emmons Winthrop Route Update

The E/W Route has really come into great shape this June. Both skiers and climbers alike have found straightforward navigation up the glacier and crevasses that are easy to end-run or cross.  

Starting from the trailhead at White River Campground, the trail is mostly snow free until about 1/2 mile from Glacier Basin Campground.  From Glacier Basin, expect snowy conditions on the Inter Glacier.  The crevasses on the Inter Glacier haven't started to show and the firm glacial ice has yet to melt out.  Rockfall early in the morning when the snow surface is firm might be the biggest hazard right now on the Inter Glacier. 

Climber and skiers headed to Camp Schurman and up to the higher pitches on the mountain should veer off the Inter Glacier and onto the Emmons Glacier at around 9200', just above Camp Curtis.  Don't get suckered into following tracks to the top of Steamboat Prow.  


Looking down at Camp Schurman and the Streamboat Prow - the red line depicts the approach to Camp Schurman from the Inter Glacier at about 9200 feet.

Above Camp Schurman the route is in incredible shape. Fairly planar and direct up the corridor, an easy traverse from the top of the corridor at about 11,800' towards the upper Winthrop, and then general switchbacks up and right until Liberty Saddle.  Above Liberty Saddle, about 13,600', the surface conditions deteriorate with ice and sastrugi making for poor skiing conditions and tricky cramponing.  

Switchback up to Liberty Saddle, fairly planar snow.  

As always, and especially with the hot weather we're experiencing right now, major route changes can occur with glacial movement and the surface conditions of the glaciers can vary drastically depending on the time of day.  

Looking up towards the summit from Liberty Saddle.
Make sure to register at the ranger station to get your permit and pay the climbing fee.  Lately, there's been lots of walk-up availability, especially on weekdays.  Hope to see you up on the mountain as the solstice approaches!

Kautz Glacier 06/01/2025

The weather over the last week has brought mostly sunny days, moderate temperatures for this time of year with freeze levels bouncing between 9-11k, and consistent north winds providing for generally pleasant climbing conditions. Still, a few brief systems have rolled through as reminders to stay prepared for wintry weather and whiteout navigation, though little new snow has accumulated. Long days and warm weather as we head into summer continue melt and change surface conditions daily.

From Panorama Point looking across the Nisqually and Wilson Glaciers at the aproach to the Kautz.


As of 6/01/2025 the approach to the Kautz from Paradise is still predominantly snow, starting at the parking lot. Crossing the lower Nisqually glacier and gaining the Wilson bench is straightforward currently and climbers' have options as to how they would like to reach the Turtle snowfield. There have been few days with freeze level below 9K recently and snow conditions are changing rapidly at low elevations. Be wary of soft and sagging snow bridges over crevasses, as well as overhead cornice and rockfall potential. As a reminder, the lower Nisqually and Wilson are glaciated terrain and traveling roped up is always recommended. 

The Turtle snowfield and camp Hazard looking up from the Castle at 9k'


From the Castle up the ridgeline along the Turtle to the rock step, multiple camp sites/tent pads are starting to melt out and running water is occasionally found in the rocks, but water maybe unavailable if the freezing level is low. The rock step is melted out with 15' of traversing downclimb to reach snow. There was a handline in place on 6/01/25, however never trust your life to fixed gear without inspecting the anchor and rope quality first and be prepared to manage this feature on your own. Traversing from the rock step into the main Kautz chute is moderate snow currently, however the traverse moves under seracs that require attention. 

The rock step looking forward

The rock step looking back, 10-15' of traversing-down climbing to a snow ledge.


The Kautz chute is currently steep snow through the first pinch, ~50 degrees, but a few more warm days may melt this down to glacier ice. The second and final step of the chute was one pitch of AI2 and steep snow. A light rack of pickets, several ice screws, and two axes were useful for this pitch. Above the chute the route continues into low angle glacier walking towards the Wapowety Cleaver. There are several large cracks in this 12-13k' zone that are bridged currently allowing for direct travel but may require long end runs as they melt out. 

The Kautz chute from the rock step. The lower pinch is still snow while the upper requires a pitch of AI2 climbing.   


Steep snow leading into the ice pitch of the upper chute.

Above the Wapowety cleaver, climber's currently have the option to head climber's left towards Point Success through the steep snow of the upper Kautz, or climber's right onto the upper Nisqually glacier and towards the Columbia Crest through lower angle terrain. Moving off the Wapowety Cleaver onto the Nisqually may increase in difficulty as the moat along the cleaver melts and widens.

Disappointment Cleaver 5/28/25


    After a busy Memorial Day weekend, climbers found a handful of days of favorable climbing weather and successful summits. After the serac fall from the upper Ingram Glacier on May 19, there have been no known climbing teams ascending the ID. All teams have been climbing the Disappointment Cleaver and holds the predominate track up the mountain for the Muir Corridor. 


DC and Ingraham Flats camp

    As for the route up the DC itself, it remains relatively unchanged from our previous blog post. Guide services have been putting in work widening and wanding the route over the past few days. With the increased climbing traffic helping to "punch in" the track, good cramponing and straightforward travel make for a fairly direct climb. There are still no ladders on the route at the time this blog is posted. A plethora of pickets above the cleaver to the summit remain as running protection options. Again, use at your discretion when deciding to clip into these. The NPS does not maintain these pickets and should be inspected by the climbing party for structural integrity in their placement.


Remaining Seracs from 5/19 collapse

    Teams are encouraged to move with purpose from Flats camp to the spine of the cleaver where the route is exposed to serac and rock fall. Please do not take breaks under the exposure on the ascent or descent. If there are other teams moving through this zone, communicate with each other to minimize traffic jams and bottlenecks where the overhead hazard is high.

Emmons/Winthrop Route Update

 After a stormy Memorial Day weekend, the route remains in great shape for climbers.  The approach to Glacier Basin continues to melt out and there's more trail than snow now, and the snow patches that are present have a fairly consolidated boot pack for reasonable walking.  Be cautious on bridges where melting snow has created a potentially hazardous crossing.  See photo below for an example.  

Depending on the weather - the Inter Glacier can either be a skier's paradise, with over 3500 feet of planar snow at an average of 25 degrees, or a nightmare with the reflective heat of the sun roasting folks with huge packs trying to ascend or storm clouds reducing visibility to near zero with precipitation turning the snow to bottomless slush.  All of these conditions occurred during the last holiday weekend and it's worth noting that skiers will have to recognize when conditions are great for skiing or when it's dangerous to be travelling on skis through this terrain.  

The glaciers above high camp continue to offer many routes to the summit.  There's the classic route up the Emmons Corridor, crossing over to the Alpine Meadow and then traversing up and right to the summit, Columbia Crest.  An alternative route traverses right out of camp to the Winthrop Glacier, ascends a steep snow slope to the Winthrop Shoulder and then directly up the shoulder to the summit crater.  With guide services ascending the route for the first time this week, a boot pack should be established, but expect some route finding and keep a track log for your own navigation purposes.  Wands are not allowed to be left on this route - so any guide service or independent who places wands on their ascent will take them on their descent.  

Surface conditions above Camp Schurman continue to be transitioning from a "winter" snowpack to a more "spring" style snowpack.  This transition makes for breakable crusts, sastrugi, scoured icy sections and unconsolidated mush - challenging ski conditions - especially when considering the crevasse fall potential associated with skiing on the glaciers.  Look for the best skiing conditions lower on the mountain - the lower Cowlitz Glacier, Little Tahoma, the Inter Glacier and in the Tatoosh.

Emmons/Winthrop Route Update 5/22/2025

The road to the White River Campground and trailhead for Camp Schurman is slated to open Friday, May 23rd - just in time for Memorial Day Weekend.  Check the park's Road Status website for more details.  Rangers have opened up a toilet at Camp Schurman and there's also a barrel outside the toilet to deposit used blue bags.

Photo taken 5/21/25 of the Winthrop Shoulder.
The approach to Camp Schurman is still in early-season conditions and though there's a bit of snow right at the parking lot, expect the first mile or so to be bare trail.  The next couple miles will be a mix of snow and trail, and then almost 100% snow covered from the switchback a half-mile before Glacier Basin Campground.  The Inter Glacier has been planar and offered decent skiing conditions this spring.  

The climbing route above Camp Schurman has had only a couple of intrepid teams on it so far this year.  Expect no boot pack, nor wands on the route and winter-like conditions.  Wind transport of new snow has created some hollow sounding slabs and false bridges barely covering crevasses.  A team of experienced skiers who've skied this route in previously great conditions, found themselves taking off their skis multiple times and belaying across crevasse bridges and even a section of exposed hard glacial ice.  They also reported large sastrugi covering most of the upper mountain above the corridor.  They recommended giving the upper mountain a couple of weeks of melt/freeze before it's back into better skiing conditions.

 

Photo taken 5/21/25 of ice on the E/W Route.
Climbers can expect a less consolidated snow surface and more effort in "booting" up the route on the upper mountain.  Keep an eye on changing conditions as the weather changes into the weekend.  Teams should be more self-reliant during summit attempts this early in the season.  Don't rely on anyone else for rescue - make sure your team has what it needs if one of your party gets injured - think stove, extra fuel, sleeping bag, extra food, etc.  

Photo taken 5/21/25 of the large and firm sastrugi on the upper E/W route.
Skiers over on Little Tahoma reported great planar ski conditions on the Whitman and Fryingpan Glaciers.  No big crevasse openings yet on either of the glaciers and the snow has consolidated more at these lower elevations.  

No matter if you're planning on climbing or skiing this weekend, be sure to stay well within your ability level!  We hope to see you this holiday weekend - and many more holiday weekends in the future!

Muir Corridor Update 5/21/25

Overview

The past week has brought high winds, new snow, and cold temps with varied forecast accuracy for the upper mountain. We observed winds in the 40-80+ mph, drifted snow on leeward regions totaling 24+ inches, and cold temperatures. Due to these conditions there has not been a high amount of traffic on the upper mountain, and teams can expect to encounter a more natural feel with less obvious boot pack in places, reinforcing the need for parties to always come prepared to use their own route-finding and navigational skills when climbing. Notable hazards right now include:

+White Out Conditions

+Serac Fall and Rock Fall

+Cold Temps

+Crevasse Fall

+Avalanche

Serac Fall at Ingraham Flats

At ~6am on May 19th a team staying at Ingraham flats reported a Serac Fall event that spread debris and ice blocks through portions of the Ingraham Direct route, within Flats Camp itself, and a few basketball sized ice blocks came to rest ~40ft downhill of camp. No one was harmed.

View from the flats, gouging on the Ingraham and blocks/debris visible (5/19, 11,000')

View of the debris from the cleaver, collapsed tents at the flats can be seen (5/20, 11,800')
Seracs at ~12,700ft on the Inghram Glacier, where the blocks originated (5/20, 12,300')

It's important to note that Seracs can fall at any time of day or night, regardless of forecasted temperature, wind events, or other factors. Forecasting when these chunks will fall is exceptionally hard if not impossible. Your best way to mitigate these hazards is to simply avoid them or minimize the time you are exposed to them. Be intentional where you take breaks, and move efficiently through zones where these objective hazards are present


Disappointment Cleaver

Route up the DC on 5/20/25

Cold temps, strong winds, and fresh snowfall this past week have helped keep the DC predominantly a snow climb, with a few short sections of rock to be encountered. Currently, the route is wanded to the summit. At ~13,700ft wands from the ID join the DC, and parties should take care to ensure they are descending their intended route. As of 5/20 there were fixed lines on the lower half of the cleaver, and many fixed pickets between ~12,500 and ~13,200.

There were no ladders present on 5/20. Teams are free to use fixed protection; however it may have been days since someone last checked or placed this gear and changing conditions may have compromised their security. Never clip into something you are not sure about and be prepared with your own kit to increase your security. As a reminder, the NPS does not place or maintain any of the fixed gear on the mountain.

Teams should consider shortening their rope length when moving through rocky areas, such as Cathedral Gap and on the cleaver, to prevent causing unnecessary rockfall that may threaten you or others. Teams are also encouraged to move with purpose from Flats camp onto the cleaver where the route is exposed to serac fall hazard from the upper Ingraham Glacier, and the Icebox climbers left of the cleaver. If there are other teams moving through this zone, communicate with each other to minimize traffic jams and bottlenecks where the overhead hazard is high.

There are several crevasses encountered near 13,500' on the upper DC route. Wind drifted snow has thinly covered many of these cracks and may hide the best place to cross. (5/20)


Ingraham Direct

Guided groups and independent teams alike have had success on the ID this season. Recently, all fixed protection has been removed from the route and most parties are opting to climb the DC due to recent serac fall on the route.


Route up the Ingraham Direct on 5/16/25

Between Ingraham Flats and 12,000ft there are a few crevasses that are beginning to open up and snow bridges that must be negotiated. Even with forecasted freezing levels this past week between 4,000ft and 6,000ft, the intense solar radiation and time with minimal or calm winds has meant that surface conditions began to soften and snow bridges were losing structure in the afternoon.

Looking up the Ingraham (5/16, ~11,200')

In the photo above, high on the Ingraham, center of the photo you can be see hanging seracs that threaten portions of the route from above. Already this season multiple parties have reported close calls and near misses with blocks falling near them when climbing the ID.

 ~12,000ft on the ID (5/16)

From 12k to Camp Comfort at just above 12,700ft the route is steeper, and more exposed. On 5/16 a handful of fixed pickets were present on the route protecting a few of these exposed traverses, and crevasse crossings. This pickets have since been removed so parties will need to come prepared to place protection for themselves and manage crossings like they would on any other route on Rainier.

Conditions Update 5/12/25

Ascending to Camp Muir is still mostly continuous snow with spots of rock beginning to show through. As snow melts, we ask that folks stick to wanded routes and snow surfaces to reduce impacts on vegetated terrain. As always it is encouraged to keep a track of your ascent route in the event that weather changes quickly - this will allow you to retrace your steps.  

Snowfield ascent to Muir 5/9/25

If climbing or skiing on a glacier or above 10,000 feet you need a permit (every time you come up to climb) and to pay the annual climbing fee (only once per calendar year). The PWIC (Paradise Information Center) is now open for the season at Paradise seven days a week 7:30 - 5:00. The White River Ranger station is still operating on a self-registration format. As always, climbers will need to pay the Annual Climbing Fee. More information can be found here

Climbing: Climbers have been ascending both the Ingraham Direct (ID) and Disappointment Cleaver (DC) route. Currently the DC has a few sections of rock and is predominantly still snow. Both the ID and DC routes had large sized serac fall cross the established routes. As always, limit time exposed to these hazards by moving efficiently and timing stops accordingly.

Emmons/ Winthrop: 

The road to White River Campground and the trailhead to Glacier Basin is plowed but still closed to vehicles.  Some intrepid skiers have been biking from the North Park Boundary to the trailhead (11 miles) when the road is open to recreational use.  Be sure to note the sign on the gate as to whether the road is open to recreational-use or not.  There's still heavy equipment working and occasionally the road will close to bikers/hikers.  The trail from White River Campground to Glacier Basin is still mostly snow, but with long patches of dirt.  It's recommended to bring shoes/boots other than ski boots.  

Both the Emmons Moraine approach and Inter Glacier approach to Camp Schurman are in good shape.  Planar snow that's great for skiing can be found on both the Emmons and Inter. One bathroom is open at Camp Schurman and the blue bag barrel is open outside the bathroom.

The climbing route above Camp Schurman is in great shape, but untraveled.  Be prepared to be self-sufficient and find your own route up the glacier - there's no boot pack or wands to guide the way.  

Looking up the lower Emmons Glacier 5/9/25

Leave No Trace: Rangers have already noted human waste on climbing routes. Do your part and carry blue bags / wag bags on the mountain... and use them! Disposal of these can be done at both high camps, in barrels outside the bathrooms with flip lids. Additionally, for those that use the public shelter located at Camp Muir, remember to pack out what you have packed in - no trash left behind - even if you think someone might utilize it.

Weather: As Mount Rainier moves into summer weather we are continuing to see active weather patterns. Over the last few days, the Park has seen sun, rain and snow with winds ranging from calm to extreme speeds. Always do a thorough weather check before venturing onto the mountain and expect weather to change quickly. Be prepared for whiteout navigation with GPS tracks and mapping tools.  Also - remember that if you venture out in extreme weather any rescue resource may not be able to help you.  Helicopters cannot fly in clouds near the mountain and rescue crews will be delayed or unable to assist in extreme winds.
