Quick report
The main hazard was cliffs shedding snow and producing wet loose. Storm and wind slab layers are rounding into a single layer with no slab-like instability observed. Riding conditions stayed reasonably good, even after a thin crust started to form with afternoon cooling.
Lots of rollerballs and small wet loose, mostly initiating in steep and rocky terrain. We observed only north and west aspects up to 5600' but would guess all aspects in this area showed signs of instability. One crown from natural slab avalanche at mid-elevations on a very steep easterly slope. Signs of dramatic glide avalanche activity from the mid-March warm-up. Could see many wet loose on the south side of Table Mt looking up Swift Creek into the Baker BC.Weather

Strong greenhousing through the morning with mixed clouds and filtered sun. Very warm in the morning but cooling in the afternoon with additional clearing. New snow amounts difficult to separate out from layers below due to warming.
Snowpack
A total of 45-60cm of snow over the warm-up crust. Layers from different snowfalls hard to distinguish. Surface wetted on all aspects from greehousing and began to form a crust in the afternoon with clearing and cooler temperatures. Generally right side up other than a moist, dense surface layer over slightly softer snow down 15cm or so. K-hard warm-up crust below new snow from the past week was 5-10cm thick with 4F melt forms below.
Avalanche
Other than numerous wet loose and rollerball piles on Anderson Butte, observed one crown from a natural slab avalanche at mid-elevations on a very steep easterly slope. Signs of dramatic glide avalanche activity from the mid-March warm-up. Could see many wet loose on the south side of Table Mt looking up Swift Creek into the Baker BC.
