Thin high clouds early, clearing throughout the day. Easterly winds in the AM shifting southerly around noon. Warm and spring-like.
No new avalanches. The most recent were wet loose to D1.5 on the SE aspect of Monitor Peak and small cornice falls in gullies but these all looked >24 hours old. Crowns from 2 large natural slab avalanches were visible in steep northerly terrain in the crater that looked several days old. Big debris piles from a few very large natural avalanches that ran in late February still visible. There was no evidence of avalanches on the on the 3/8 Facets/Early March Crust on the southside of Helens.
The snowpack was strong and spring-like. A firm, boot supportable crust at the surface gradually thawed throughout the day. Snow softened by noon for pleasant corn-like turns on sun-exposed slopes 7000ft and below. Above, snow surfaces remained frozen and icy. The Early March Crust was found ↓80-100cm below the surface near and above treeline. In one test pit (ENE, 5900ft) the 3/8 Facets were rounding, moist, well bonded to the Early March Crust below, and did not fracture in snowpack tests. Continuous snow exists out of the Marble Mountain SnoPark at 2600ft and the Worm Flows route is in nice shape.
