May 29, 2020 update

Sunrise: 5:22 am

Sunset: 8:51 pm

The road to Climber's Bivouac is CLOSED. Climbers can climb out of Marble Mountain Sno-Park (winter route). No parking pass is required at Marble Mountain. There are pit toilets available at the trailhead, but no running water, and bathroom services may be limited so please bring your own toilet paper, soap, water, or hand sanitizer. Please plan accordingly. A pre-purchase climbing permit is required and climbers must register in the log book at the climber's kiosk before climbing.

The road to Marble Mountain Sno Park is paved and free of snow. Please climb with your quarantine household, and maintain at least 6 feet of space between yourself and other hikers. Please review our Mount St. Helens and COVID-19 page to learn about open trailheads and sites, expected services, and how to recreate responsibly. Consider bringing a mask to put on when you pass others on the trail.

There is no snow in the woods at the parking lot of Marble Mountain Sno Park. The first two miles of trail through the trees has little snow, and is melting rapidly. Above treeline is firm packed snow in the gullies. Ridges up to the seismic station (5,800') are snow-free. Along Monitor Ridge above 5,800' there is snow to the summit, and there is risk of post holing near rocks.  A snow cornice is hanging over the crater rim, please stay back 30-40 feet. Skiing is possible down to the treeline.  An ice axe, and crampons/microspikes are still advised for early morning travelSki crampons and skins are also advised for those ascending on skis/splitboards. Snowshoes are not necessary at this time.

On the descent, glissade chutes are present but take caution- it is easy to descend away from the climbing route, especially between the monitoring station (5,800') and treeline (4,500'). Do not just follow the "fall-line" on your descent. Route finding may be challenging in dense cloud or fog; be sure to know the route and carry navigation equipment.

Please check the forecast as conditions can change rapidly.
