Clearing Above the Mist

Washington locals already know, but for those of you "out-of-towners" the month of July has been unusually stormy. Right now there is 100' visibility in Paradise (elev. 5400'). This has hampered many climbers on approaches and backcountry skiers with navigating. Luckily, even with all the poor forecasts, the upper mountain has stayed clear and relatively calm.

Climbers have been out gettin' it done. The storms below offered amazing sunrises and sunsets. Both standard routes (Emmons/Winthrop and Disappointment Cleaver) are still in great shape - as well as most non-standard routes. Climbers utilizing both the public shelter and the bathrooms at high camps should remember that these facilities are for them; please keep them clean. Do not leave trash, any food (even unopened food), or equipment behind - "leave no trace."

The photo above and right is from the shoulder of the Emmons Glacier earlier this week. These great conditions won't last for long! Hope to see you on the mountain.

Nisqually Rock Avalanches - Frequency and Size

For those of you still watching these large rockslides from the Nisqually Cleaver, here's a little more information for you. I called Kate Allstadt of the Earth and Space Sciences Department at the University of Washington and asked her for some seismic data that may show a better picture of the frequency of rock avalanche events.


She was able to graph some data that shows the distribution of the major rock avalanche events over the period from June 24th to July 7th. You can see in the graph that there is a trend decreasing in frequency and size. So it appears that the danger could be abating - but only gradually.


I must say that this correlates with direct observation, as there have not been any major rock flows down the mountain in the last week or more. The lowest extent of the largest debris path is to an elevation of about 8200 feet. Here is a graph Kate produced that shows the data from the seismic sensors installed on Mt. Rainier. The horizontal axis represents the date. The vertical axis represents the number of events per hour. The top row identifies single and large events.

Peak of the Season

Snow on most approaches has started to consolidate with the melt/freeze cycles we've been having. This makes boot-packing to the routes much more feasible. All of the roads in the park, except the Mowich Lake Road, are open to cars. The road crews hope to have Mowich Lake open by the end of July - there's still seven feet of snow at the lake!

At Camp Muir there are now three gallon and five gallon buckets with lids for food storage. The buckets are kept in the Public Shelter for anybody to use. After use, please return the buckets, cleaned out, to the Public Shelter. Hopefully, use of these buckets for food storage while you are climbing or sleeping will help deter foxes from becoming habituated.

Other peaks within the park have been seeing some climbing activity too. Pinnacle Peak, Castle Peak, Little Tahoma, and Pyramid Peak saw ascents this last week. Climbing in the park is about to peak, and stay popular for the next couple of weeks. Statistically, climbers have the best chance of success in July.

Sun-cups are growing larger and the grit is melting out making skiing conditions more challenging. Skiers descended the Wilson Headwall, Fuhrer Finger, Disappointment Cleaver, and Emmons/Winthrop, but all of them reported conditions are worsening - so get up here quick while there's still pleasant turns to be had!

Happy Independence Day!

Happy Fourth of July! Remember firearms are allowed in the park, but fireworks are not.

The weather and climbing conditions came together to make an amazing weekend. A windy low pressure front passing through on Sunday morning made things interesting - but it passed by quickly giving way to the best weather of the season. Climbers have been on Ptarmigan Ridge, Mowich Face, Success Cleaver, Kautz Glacier, Disappointment Cleaver, Little Tahoma, Emmons/Winthrop, and Liberty Ridge. It's as if the poor weather early this season preserved the mountain for great climbing in July. Suncups are starting to form on the south and west facing routes,making skiing on the upper mountain less fun, but cramponing much easier. Be safe, see you on the mountain!

Large Rock Avalanches on the Nisqually

OK, folks, there're some major rock avalanches happening on the Nisqually Glacier. Anyone venturing near the Nisqually or even traversing across it lower down to get across to the Fan should read this post. We're not talking about a bunch of rocks, but many thousands of tons of debris in a 50' wall of snow, ice, water, dust, and rock coming down the glacier that would outrun anything in its path.



Rangers, climbers, and guides at Camp Muir first were aware when these series of slides started on the 24th of June. Rangers reported feeling the earth shake and hearing a very loud rumble. Indeed, you can tell from extent of airborne dust in the picture above that it must have been loud. Shortly after the slide occurred, the geologists at the Cascades Volcano Observatory called us and asked us what was up. Below is the seismograph reading during the event.
Here's a quote from one of the original emails between the NPS and USGS. - "FYI about 10 minutes ago the climbing rangers at Camp Muir saw what they all described as the biggest icefall they've ever seen come off the Nisqually. A guide party at 8,000 ft on the Wilson glacier reported that it had multiple fingers & traveled down to about 7,800 ft. They also described it as the biggest icefall they've ever seen anywhere.
The rangers at Muir described the debris as a mix of rock & ice and being about 50 feet thick but couldn't judge the acreage covered as it is hard to see the entire run-out zone from Muir.
" from Ranger Ben Guttridge.

After I heard about the slide, and saw it from my house in Packwood, I decided to hop in my airplane and take a ride towards the mountain to get some pictures as close as I could.


All in all, there have been three slides of this size in the last two days. Right now, we don't recommend crossing the Nisqually Glacier at all - although at this time, the park has not declared a "closure" of the area. If you are intent on doing the Kautz Glacier route, think about accessing the base of the route by Comet Falls trailhead.

Foxes Feast on Food

Two foxes (of a rare sub species) are currently moving up and down the mountain from Paradise all the way up to the summit. While the mountain is their natural environment, the food they have been eating this year has not been coming from the mountain, most of it has been taken from climbers and day hikers at Camp Muir. Foxes have been consistently searching out food left in backpacks and tent vestibules.

Sadly, we have experienced what happens when foxes become habituated and dependent on humans in the park - we lost our friend Pickles.


Mount Rainier is home for these foxes, meaning we can't relocate them nor would we want to. At this point we are trying our best to have the foxes and climbers interactions be kept to a minimum. Please help us with this effort by maintaining a clean camp and storing all food zipped up, inside of your tent. Day hikers and skiers please be tidy during snack breaks and clean up your scraps (both food and wrappers). Thanks so much for your help!

Sending in June

Generally awesome climbing conditions have led to many teams summiting these past couple of days. Check out the trip report by Olympic Mountain Rescue on the Kautz Cleaver. This is a classic ridge-top line giving spectacular views down the southside of the mountain and a raven's point of view of the Kautz Glacier's ice pitches.
A couple of nice pics were also snapped by rangers in the Sunset Amphitheatre. The westside routes are as remote as ever and offer extreme climbing opportunities along with a moderate descent route (via the Tahoma Glacier).
