Recreational Observation

Source Lake - Big Trees - Pineapple Pass - upper Denny Creek SW aspects - return same

March 8, 2019, 4:40 p.m. PST

Weather: Mainly cloudy, calm winds, good low-mid elevation vis into surrounding terrain, temps 18-34F

Snowpack: Spotty 3-4mm surface hoar up to treeline. 20-25cm of uncohesive recent storm snow sits on a variety of older surfaces ranging from wind affected layers (1F hard), to thin wind slab (1F-P hard, ~15cm thick), to well-settled storm snow, to a melt-freeze crust on solar aspects (2cm thick). Very little wind affect in most recent snow, but a high degree of variability in upper snowpack structure is still evident from recent winds. Snow profile in Great Scott Bowl, 4840ft, NE, HS 290cm, 2/3 MFcr down 145cm. Recent storm snow vary well bonded to the old/new interface. Mainly hard, resistant planar, results in small column tests on various older interfaces in the upper meter, most notable down 65cm on a slight density break (no facets or SH observed here). Denny Crk, SW, 4400-5200ft, 20-25cm of recent snow unreactive to ski tests (not enough slab structure or depth) but failed easily, sudden planar, in shovel tilt tests on preserved large stellars crystals.

Area Description: Alpental Valley

Avalanches: A few very small Loose Dry in steep terrain along Alpental road, otherwise, no notable new avalanches.
