The road to Climber's Bivouac is CLOSED. The winter climbing route (Worm Flows) out of Marble Mountain Sno Park is the preferred climbing route for winter and spring. After March 31st, a Sno Park Pass is not required to park at Marble Mountain Sno Park. Dispersed camping is available around the Marble Mountain parking lot. There are pit toilets available, but no running water or trash service. Please plan accordingly.
The road to Marble Mountain is plowed with some snow and ice on the road, and the parking lot is mostly clear with thinning snow in the woods up to Chocolate Falls. Between Chocolate Falls and Treeline (3,700' - 4,800') there is 10-12 ft of snow, with a thick layer of soft snow present all along the route. Snowshoes would help travel in areas of thick or soft snow. Icy conditions may exist at higher elevations. Be prepared for high winds that bring varying amounts of precipitation. The summit does have a cornice 10-20' overhanging, please stay back from the edge! If you can see into the crater, you are too close, and cornice may collapse. Beware of post-holing through snow bridges on the way down, when snow becomes soft in the afternoon. Snowshoes help to mitigate risk. High temps in the next week means loose, wet snow. Be aware of avalanche terrain and familiarize yourself with avalanche danger.
Please check the forecast as weather conditions as mountain conditions can change rapidly.
