Upper Mountain Climbing Conditions: Parties have been summiting via the Ingraham Direct route above Ingraham Flats. The route ascends the Ingraham Glacier until 12,700 feet, where it ascends to Camp Comfort above Gibraltar Rock. From there, the route continues upwards with a slight detour around large crevasses just below 14,000 feet. The route meets the crater rim at Guide Rock.

The upper mountain snow surfaces are firm for this time of year. A mild winter combined with a high-elevation rain event at the end of March has made conditions resembling smooth and firm, hard packed snow. As a result, guides are using several pickets on their climbs to protect areas of the route with fall hazard. If you have and/or use pickets on your climb for running protection, it's important to practice a procedure with your team for navigating them before your climb to enable you to move through these areas efficiently and not disrupt the movement of teams around you.

Also of note, there have been a couple instances in the last week of climbers and skiers being caught in avalanches. Consult the Northwest Avalanche Center's West South Region Observations for more information.

Springtime Conditions Update

Mt. Rainier from canyon rim overlook on April 20th

 Happy springtime!

Climbers and skiers are are beginning to venture onto the higher slopes of the mountain. Park operations are winding up, and the road to Paradise is open 24 hrs a day. Expect intermittent road closures above Longmire when inclement weather impacts the park and during heavy snowfall events.

For weather-related trip planning assistance, check out the Mt. Rainier Recreational Forecast from the National Weather Service. 

This Weekend (April 25-26, 2026)

The forecast this weekend calls for sunny skies by Friday morning and relatively cool temperatures with freezing levels staying well below Camp Muir. Saturday afternoon, expect high clouds and possibly a cloud cap near the summit. Winds at Camp Muir are forecast to be 10-15 mph Friday and Saturday, while winds on the summit will slowly decrease from 55 mph on Friday to 25 mph on Saturday. Wind direction will be NE-N-NW. By Sunday, the upper level low pressure system to our north moves closer to Mt. Rainier, resulting in a chance of precipitation and reduced visibility on the upper mountain and Muir Snowfield by Sunday afternoon.

This Week:

The mountain received a significant amount of precipitation over the last two days. Accumulated precipitation at Paradise Thursday morning is almost 2 inches. This precipitation fell as a mix of rain and snow across the Park, resulting in only 8 inches of new snow at Paradise. As we move up the mountain, expect higher snowfall totals once you get above the rain line. Additionally, winds at Camp Muir gradually increased with the new precipitation. 

Average wind speeds of 15-30 mph, and gusts up to 40 mph definitely transported the new snow on the Muir Snowfield and the upper mountain. Wind direction at Muir switched from south to northwest mid-storm. New snow and high winds from opposite directions have surely created elevated avalanche hazard on the upper mountain. Travel cautiously and look for signs of instability like cracking on stiff snow surfaces, or recent avalanches on adjacent steep slopes.

Expect intermittent snow coverage for the first couple miles above Paradise. Adjust your route to stay on snow as much as possible.

Muir Snowfield:

Snow coverage is below average for this time of year below 8,000 ft on the snowfield. Areas between Paradise and McClure rock have exposed rock fellfields and fragile alpine plants. Please avoid walking on any surface besides snow on your way up the snowfield. Above Panorama Point, head towards the summer trail (snow covered) near Pebble Creek. The traditional winter route to McClure rock and traversing near Sugarloaf is not snow covered enough to protect the fragile alpine plant life from damage.

Camp Muir on April 20th

Conditions at Camp Muir are quite icy and slick. High winds likely scoured much of the new snow to leeward areas. Crampons may be useful for walking around camp if you plan to spend the night.

Few parties have ventured above Camp Muir recently. Rangers observed firm conditions at and above Camp Muir on Monday, April 20th. With limited information about upper mountain conditions, our advice is to set conservative mountaineering goals and methodically evaluate conditions on any ascent. This winter brought unique weather to the Cascade Range, which will result in unique and surprising conditions up high.

Access and Permits:

• Please arrive having already paid your climbing fee: here.
• Wilderness permits are issued via self-registration in the foyer of the small A-frame ranger station at the upper Paradise parking lot. Or at the Longmire Wilderness Information Center

Facilities and Emergency Infrastructure:

• The public shelter at Camp Muir is closed. The door is boarded and locked. Planned repair work was not completed in the fall.
• Access to the shelter is emergency-only and requires using the emergency radio to contact dispatch. Declaring an emergency to gain access will initiate a rescue response.
• The emergency radio has been relocated to the first restroom building nearest the helipad. This restroom is unusable for any other purpose than using the emergency radio.
• The pit-toilet is open and available for use. Find the second bathroom structure on the ridge, to the east of the helipad.

Equipment and Self-Sufficiency:

• Bring the full complement of winter camping gear necessary to remain self-sufficient—even if your plan is to camp only at Camp Muir.
• Leave the parking lot with detailed maps, whether digital or paper.
• If relying on a phone, bring an external battery, use airplane mode, and save social media posting until after your climb.

Search and Rescue Realities:

It is critical to understand how early season rescue differs from summer operations:

• During the summer season, climbing rangers are staffed daily and often stationed at Camp Muir and Camp Schurman, with dedicated training and aviation support.
• This infrastructure does not exist early season.
• Reaching an injured climber may take a full day or many more, even in favorable weather. In some cases, depending on location, conditions, and weather, no team may be able to respond for several days.

If you are injured on the mountain—particularly above high camps—the likelihood of same-day assistance is significantly reduced.

Winter Climbing

Happy New Year!

A stretch of relatively clear weather is currently forecast between January 13 and January 20, and we want to take a moment to share current conditions and several important considerations for anyone planning a winter climb of Mount Rainier.

Winter Weather Windows and Climb Success

Statistically, dry weather windows like this occur most years between mid-January and mid-February. Historically, there is a noticeable increase in summit success during this period, often peaking around the third week of January. Success rates during these windows can approach typical summer averages of 55–60%.

However, the devil is in the details.

Winter climbing on Mount Rainier is inherently difficult to plan. While these short weather windows do occur, they tend to favor climbers who live locally, have flexible schedules, and—most importantly—have significant experience on the mountain during the regular climbing season.

For teams with limited experience in glaciated terrain or winter alpine conditions, this may not be an appropriate time to attempt your first climb.  Let's dive deeper.

Access and Permits

• Please arrive having already paid your climbing fee: here.

• Wilderness permits are issued via self-registration in the foyer of the small A-frame ranger station at the upper Paradise parking lot.

Facilities and Emergency Infrastructure

• The public shelter at Camp Muir is closed. The door is boarded and locked. Planned repair work was not completed in the fall.

  • Access to the shelter is emergency-only and requires using the emergency radio to contact dispatch. Declaring an emergency to gain access will initiate a rescue response.

• The emergency radio has been relocated to the first restroom building nearest the helipad.

Equipment and Self-Sufficiency

• Bring the full complement of winter or arctic camping gear necessary to remain self-sufficient—even if your plan is to camp only at Camp Muir.

• Leave the parking lot with detailed maps, whether digital or paper.

  • If relying on a phone, bring an external battery, use airplane mode, and save social media posting until after your climb.

Search and Rescue Realities

It is critical to understand how winter rescue differs from summer operations:

• During the summer season, climbing rangers are staffed daily and often stationed at Camp Muir and Camp Schurman, with dedicated training and aviation support.

• This infrastructure does not exist in winter.

• Reaching an injured climber may take a full day or many more, even in favorable weather. In some cases, depending on location, conditions, and weather, no team may be able to respond for several days.

• The park does not maintain an exclusive-use helicopter contract during the winter.

If you are injured on the mountain—particularly above high camps—the likelihood of same-day assistance is significantly reduced.

Avalanche Conditions

Finally, stay tuned in to the snowpack.  Use the skills you learned in your US Level 1 and 2 courses.

• Although we've suffered through extreme weather events in the last three months, both droughts and atmospheric rivers, there is A LOT of new snow on Mount Rainier.

• The high elevation of Mount Rainier presents its own unique avalanche phenomena neither exactly like continental nor maritime environments!

Conditions Update @ Muir, Wednesday January 14, 2026

Made it to Camp Muir this morning for a quick conditions check.

• Pan Point is a little confusing as there is a lack of snow.  I think the normal winter gulley is the good call.  The summer trail is steep and there is a nice cliff under the traverse track making the consequences of a fall rather dire!
• Conditions were smooth as the sun worked its magic up to about 7500.
• 7500 onwards the snow became increasingly firm.
• By 9000’, yeah it was kind of terrifying.  Definitely recommend ski crampons.
• Took off skis at 9800 and booted it the last 200’
• Muir is “iced-in”.  All that moisture from a month ago is water ice all over Muir.
• It took me 10 minutes to make my way over to the public shelter from the ranger station!  I recommend crampons or micro-spikes just making your way around Muir.
• The toilet is iced-in.  I recommend blue bagging your waste so grab those at Paradise before you head up!
• I’ll post some photos here when I make it back down tonight.

Don't forget to pay the fee and self-register at the Old Station and have a great time!

Winter Season

First - the Public Shelter at Camp Muir remains CLOSED. It will remain closed until the Park Service can finish up the remodel and get the equipment out of the structure.  In the case of an emergency, the emergency radio is now in the first toilet next to the helipad.  You'll see the antenna on the roof of the building.  Make a call to "Dispatch, this is the [Last Name] party at Camp Muir".  You'll hear "This is dispatch, go ahead."  Then state your emergency and desire to use the public shelter.

Conditions on the upper mountain have changed - a thin blanket of new snow now covers the skeletal glacial ice and rocky ridges above high camps.  Unsettled weather for the next couple days will continue to add snow to the upper mountain and make conditions difficult for any summit attempt.  During this winter off-season there are virtually no other climbers on the mountain.  Guide services ceased operations weeks ago, and rangers are only sporadically staffing high camps for end-of-season projects.  

Any summit attempts this time of year should be considered a serious venture - it's definitely not the time of year for parties to attempt the mountain for the first time.  All parties who climb this time of year should be self-reliant and carry extra equipment so that they have contingency resources.

ALL CLIMBERS MUST:

1. Pay the climbing fee

2. Obtain a climbing permit

You can pay the fee online at Pay.Gov and you can obtain a permit via self-registration at Paradise and at the White River Ranger Station.  Please remember to check out after your climb by submitting your climbing permit back at the ranger station after your climb.  See the blog post below for more details on registration now that it's the "winter" season.  

These moments of transition from late summer to the start of winter add extra hazards.  Thinly covered crevasses, new avalanche problems, longer storm cycles and colder temperatures can all add up to dangerous conditions.  Please use extra caution in any winter climbing or skiing attempt.  And, while it can be rewarding to have solitude up high on the mountain, please do it safely!

Have a great winter and see you next spring! 

Climber Self-Registration Begins September 11th

Where did the summer go? With the return of fall, operations and services at Mount Rainier will begin to decrease. Climbing Permits are still required through the fall and winter for traveling on Mount Rainier above 10,000 feet or on glaciers. Self-registration for climbers in Paradise begins Monday September 8th, 2025 and the Paradise Wilderness Information Center will close September 7th. There will be a self-registration box located outside the Old Ranger Station in Paradise. As winter approaches a large tunnel will be put in front of the door of the Old Station to keep the Self-Reg kiosk and stairs snow-free. Walk through this tunnel and find the self-registration box with instructions at the end of the walkway. This is open 24/7 for registration, even if no one is staffing it - follow the directions on the kiosk.

Self Registration is at the Paradise Ranger Station near the center of the photo.

Climbers can still register in-person (which we recommend) in Longmire and White River Ranger Stations. Check the park's operating hours and pay special attention to the date at which the operating hours change as we move into winter. The White River Wilderness Information Center will be staffed until October 9th, 2023. After that date, there will be a self-registration box on the outside of the Wilderness Information Center as well until the road closes for the season. The Longmire Wilderness Information Center will also close around then and move their operations to the Longmire Museum for the winter. 

There are two things required to climb in the off-season. The first is to pay the online Annual Climber Cost Recovery Fee. The second is to use the self-registration stations at Paradise or White River to fill out your permit. 

Filling out your self-registration permit completely will help any necessary search and rescue efforts - please take the time to get it right! The full list of instructions will be located at both self-registration stations. You will fill out a sheet (front and back) at the ranger station and leave it in the drop box, you don't carry the permit on you. Please remember when you get off the mountain to fill out the return slip at the station and put in the drop box as well to check out from the field. 

As summer turns to winter, our seasonal staff starts to migrate away from the mountain. High camps will only be staffed very occasionally, search and rescue operations will be delayed, and the park's exclusive-use SAR helicopter will be departing the park by late September. Please keep in mind that during the winters, there aren't rangers actively staffing the high camps to talk about conditions or weather. It is recommended that climbers are prepared to be very self-sufficient as any rescue efforts could take days! 

Disappointment Cleaver 9/8/2025

Welcome to September! 

As we move further into late summer season, conditions on the mountain have been rapidly transitioning from the snowfield to the summit.  Here's a quick run down on what's going on right now and into the winter on the mountain:

Muir Snowfield:

As stated in the previous blogpost, all parties headed up the Muir Snowfield should be prepared for sections of bare-ice, flowing water, and crevasses large enough to fall into. Please be ready with traction devices for footwear such as micro-spikes or crampons, trekking poles, and gloves. These icy and crevassed sections can catch people off guard if not properly prepared.  Be especially cautious if we get a fresh dusting of snow which can hide these hazards from view.  

Camp Muir:

Remember that the Public Shelter at Camp Muir remains closed through September, and all climbing parties will need to bring their own tent/shelter.   This makes conservative decision making during stormy weather important - there's no backup shelter to retreat to during lightning storms.   

Significantly sized crevasses have opened up in camp and continue to grow with warm temperatures.  This makes finding a campsite at Camp Muir difficult.  Please plan on camping on the snow, double check that your site doesn't have crevasses underneath and isn't prone to rockfall, and bring a shovel or adze to flatten out the tent site.  The crevasses near Camp Muir are now large enough a person can certainly fall in.

Please travel around camp with caution - there's been active rockfall on the ridges around camp and the danger of an unroped crevasse fall cannot be overstated.  

Disappointment Cleaver Route:

The upper mountain swiftly moves into "late season" conditions with significant crevasse, serac fall, and rockfall hazard throughout the route. 

All three guide services AAI, RMI and IMG have officially ceased guiding operations for the season, citing deteriorating conditions at the Cleaver entrance and upper route as the primary factors for this decision.  They've pulled all of the route adjuncts - no more ladders, hand lines or "fixed-pickets" are in place right now.  This means that any independent climbers must be prepared to navigate around large crevasse openings and prepared to protect steeper loose rock steps.  

The entrance on to the Cleaver has been the primary limiting factor for both guided parties and independent parties alike due to significant objective hazard. A widening moat between the Cleaver and Ingraham Glacier at 11,400 feet coupled with excessive rockfall and poor footing poses a risk decision that climbing parties must assess for themselves. 

Above the Cleaver, conditions have also continued to degrade without regular maintenance provided by the guide services. Independent teams should plan to navigate without relying on previously installed equipment and be prepared for complex route-finding and rapidly evolving hazards.  There will not be wands on the route marking a way to the summit.  

Late-season climbers should exercise heightened caution, assess conditions carefully, and have technical skills necessary for a truly independent and an unguided route. Good teamwork and conservative decision making are paramount for a successful trip on Mount Rainier.
