Name: Ben Pritchett


Zone: Northwest Mountains
Location: Elkton area
Aspect: South East, South, South West, West
Elevation: Near and Above Treeline


Avalanches: One tiny fresh wind slab off the Treasury to Galena ridge.
Weather: Ridgeline Wind Speed: 10-20 mph
Ridgeline Wind Direction: NW
Wind Loading: Previous
Temperature: 15 F
Sky Cover: Few
Weather Description: Clouds increased late morning through the afternoon. Light to moderate northwest winds.
Snowpack: Travelled over alpine south and southeast-facing slopes. Near treeline we travelled on east through south to west. No cracking or collapsing observed. A week ago on a similar route in the same terrain collapsing was common near treeline, but not above. Overnight northwest winds transported snow only near alpine ridgelines. Drifts were soft and posed no threat.
