Route Update // Ben Wicks
One of the challenges of a late summer attempt on Mt. Rainier is that large crevasses tend to open up, snow bridges become soft, and rock falls become a higher risk. Given the unusually warm summer we have experienced, these conditions become exacerbated. The good news is that our equipment and training provide a strong level of protection against these risks. And, of course, a clear head to judge and evaluate risk along the way up is crucial. Ed Viesturs, a local Seattle mountaineering hero, says it this way…“Getting to the top is optional, but getting down is mandatory”.
Below is an update on the conditions of our route up to Camp Muir and beyond .
August 12th
Muir Snowfield
Numerous crevasses have begun to open on the snowfield below Camp Muir between 9,200 and 10,000 feet. Although some of the known crevasses are wanded, the intense heat has been melting out the snow bridges faster than wands can be placed. The current trail travels over bridged cracks that are up to six feet across. Use extreme caution as you move above Moon Rocks on your way to camp. The recent rains have melted out a large amount of the snow above 9,000 feet leaving behind exposed and slick blue ice that requires crampons for secure footing.
Disappointment Cleaver
Late summer weather and climbing conditions have been prevailing themes on Rainier recently. This has made for a high summit success rate and even some t-shirts on top of the peak! Rockfall and melting snow bridges are the two primary risk management concerns affecting the route currently.
The cleaver has completely melted out and all travel is now on rock. As you travel along the cleaver, aim for the spine and slightly left of the spine for the most efficient and least exposed route. This route is wanded but the flags can be difficult to see under headlamp before the sun rises each morning. Be mindful of those travelling above and below you. Avoid kicking rocks or snagging them with your ropes as you move up and down the path. If you happen to dislodge a rock, alert others immediately by yelling ROCK!
The recent string of hot, bluebird days have affected the mountain’s snowpack drastically. Crevasses have been observed opening up by a foot or more in the span of a day during the warmest stretches of weather. Snow bridges are becoming very weak and the trail is becoming extremely narrow in places. The two fixed lines on the route, below and above the cleaver, have paths that are at most six inches wide. These thin routes require careful footwork with crampons to avoid accidental spike snags in gaiters and pant legs. The intense daytime sun has been weakening the picket placements that support the fixed lines. Be sure to test any gear that is in place on the route as its strength will vary widely throughout the day. The end of the traverse over onto the Emmons shoulder is beginning to break apart and requires running protection at this time.
With all of that said, the route is still pretty direct and generally in good shape as we near mid-August. Weekends continue to be near capacity up at Camp Muir and Ingraham Flats but the weekdays have been seeing much less traffic. Hopefully the weather fronts this week will bring some new snow and colder temps to help preserve the route for a while longer this season.
