Perley rock

Skied up Perley Rock, dropping in skiers right. Quite a few other parties in the area. Saw a mix of new and old looking avalanche activity, most noticeably a reasonably new looking size 2 midway down the northeast flanks of castor and pollux originating in a steep cliffed area in the glacier. A couple of very small windloaded convex rolls in the vicinity of Perley Rock had also slid during the past few days. Couldn't say if they were natural or skier remotes. Surface hoar starting to form at and below treeline.
