7 - 8
FATMAP difficulty grade
Start at the end of Moose-Wilson Road (either north from Moose or south from Wilson works).
Skin along the groomed road until reaching the Phelps Lake summer trail.
(Should see a skin / XC ski track.) Cross the lake, then pick up a skin track up the east ridge of Prospectors.
Drop in for Apocalypse is at ~10,150’.
You’ll find a rappel anchor on a tree.
Two rappels needed — we used two 60m ropes.
Second rappel station is on a rock half-way to the “cave.” Two chokes on the descent — one before the turn right, then second toward the bottom.
Second choke might require a rappel (anchor on skiers right, or build a V-thread in the ice).
We were able to side-slip during a good snow year. Ski along the Death Valley summer trail, then (1) skin up the ridge on the northwest border of Phelps if you started from Moose, or (2) ski / skate over Phelps Lake if you started in Wilson.
