Several new natural wet loose were observed late in the day Saturday on steep south aspects on Skyscraper above the summer road.
Arkose ridge slab/sluff combo happened on 3/7-8 (fake spring inversion event) with some additional new wet loose in the past few days.

Observer Comments
Toured in this area on both 3/31 and 4/1. On 4/1, there appeared to be a few small wet loose slides on steep south to west aspects below rocks that may have occurred late in the day on 3/31 (after we left at 4 PM)... but this activity was not widespread and smaller than slides from last week before the dusting of snow Thursday. We also saw a few wet loose on Arkose Ridge while approaching Skeetawk on 4/1; didn't see these yesterday but may have missed them! See photo below.
Weather
SUNNY. Few clouds transitioning to clear during the day.
Temps at 3000' in the 20s in the AM, 32 when leaving at 3 PM.
Calm except brief light west winds at our high point of 4000'
Snow surface
The 2-3" of new snow from Thursday night remains soft with no signs of sun on north to east, 3000' and above... and a dry snow surface at 3000' on non-solar aspects midday! Low angle southerly slopes were left with a very thin crust from yesterday's sun. 2mm surface hoar formed overnight, and was more noticeable up high.
Snowpack
Dug a quick pit on the northerly aspect just north of $1000 run - results/structure is below!
Wet loose activity that may have triggered or ran into small crowns on a steep southerly aspect of Arkose Ridge, just as you enter Hatcher Pass on the right. They looked relatively new, potentially from late in the day yesterday? Or we just didn't see them Friday!
Snow structure/results just north of $1000 Run
Northerlies remain crust free... for now!
