Very wind affected terrain in the Bullmoose/Mt Spieker area today. Skinned up the W side of Spieker to 1400 m on the atv trail. Observed several instances of whumphing in sheltered areas. Dug a quick pit, snowpack is very consolidated and right side up. No observable signs of avalanches on any aspect or elevation.

Snow conditions were: Crusty, Heavy, Wind affected, Powder. Weather conditions were: Windy, Warm, Sunny. We rode: Mellow slopes, Dense trees. We avoided: Alpine slopes, Steep slopes, Convex slopes. Riding quality was ok.

Avalache Conditions: Whumpfing or drum-like sounds or shooting cracks.


Snowpack depth is highly variable, from exposed ground on windward slopes to deep powder and drifts in leeward areas. Found multiple failures in moderate range of top 50 cm of drifted snow but no propagation. Snowpack is very consolidated and right side up. Dec 7 layer was down 100 cm and well bonded.
