Comments:
Mt McCausland. Natural avalanche D2.5-3. Likely ran midday on 16th. Crown estimated 50-70cm deep by 400m wide. Couldn't see debris.
We saw many other debris piles ranging in age from today (sun-triggered point releases on solar to D2) back to the 13th. We couldn't make out many other defined crowns with intermittent visibility.

Winds were light near treeline. Recent wind features were stubborn at 5300ft ridge. Minimal wind effect in the snow that fell overnight.
Ski pen 30-40cm. Boot pen >100cm, almost chest-deep and difficult to measure.
