“Great moderate and widely spaced tree skiing.”
Type: Backcountry or Sidecountry
Fun mellow skiing with enough trees to make it more interesting than just a mellow open slope. There is steeper and more featured lines skiers left of the drawn line.
Usually accessed by gaining the Castle Peak/Andesite Peak saddle and either ski some of the NW facing treed slopes down to Round Valley, or a more mellow and more direct traverse across Round Valley. Then skin up your line. For a bigger day it can be fun to ski the N/NE slopes of Castle Peak, skin up the NE Castle Peak slopes then traverse the ridge (often icy and rocky) that connects Castle and Basin.
Popular slope/peak for people staying in the Peter Grubb Hut that sits just west of the treeline of Round Valley.
A little far out for most people to do laps on (which keeps it from being skied out fast) but would be worth it if you want to get your vert in for day trips.
The true peak is often pretty wind swept/icy. Often start a hundred feet or so below the true summit just to avoid the those conditions.
