Snowplay in the Mammoth Lakes Basin ▣

Starting from the winter closure at the end of Lake Mary Road, walk up along the Lakes Basin Winter Public Access Corridor on the left-hand side of the road to the green trail system sign at the summer Panorama Dome Trailhead. Hike or snowshoe all the way to Horseshoe Lake. Stay to the left-hand side on the way out, off the fee-based nordic trails. Enjoy numerous vistas along the way of the Mammoth Crest and the backside of Mammoth Mountain. Look for snowplay opportunities along the sides of the access corridor and up the wooded slopes of Panorama Dome. And keep your eye out for downhill skiers descending through the "Hole in the Wall" lava tube across Twin Lakes.

Avalanche Forecast for 02/21/2025

AVALANCHE FORECAST: A small Wet Loose avalanche, a cornice falling, or the weight of a person could trigger a dangerous avalanche breaking deep within the snowpack. Choosing low-consequence terrain with low slope angles, avoiding slopes with hazards overhead, and maintaining wide safety margins are the best strategies for managing the avalanche problems.
