Recreational Observation

Field day with an AIARE 1 course, toured up to Source Lake and the Rap Wall/No Fog zone for terrain identification and travel technique practice.

March 18, 2017, 1:30 p.m. PST

Weather: Moderate rain switching to moderate and heavy snow at 09.30-10.00 at 3500' elev. Snow rate varied throughout the day but remained constant.

Snowpack: As reported, old snow settled, moist, and reset. Friday night's HST was up to 8" at 3900' elev. Also at 3900' we observed a light rain crust aprox. 3" down that was not present at lower elevations.

Area Description: Alpental Valley - Source Lake via low route / waterfall approach.

Avalanches: Bryant Couloir (aka Wahoo Gully) ran R5 D3+ sometime since NWAC Pro Observations on Wednesday - Thursday suspected because of heavy rainfall and storm snow coverage. Unable to see start zone or track due to low cloud cover and weather. Debris and runout reached and entered Source Lake, stood over 2m deep and 100m wide. This is making the traverse out from Source Lake into the basin for the Snow Lake Divide skin track challenging. Multiple D1 loose wet slides between Little Annie's, Wall Street and the Mushroom Couloir have completely covered the winter skin track and will require care to travel through.
