Route & General Observations

From the Glen Alps trailhead we hiked up O’Malley gully, across the Ball Field, down onto Black Lake, and dropped into the Middle Fork Campbell creek drainage. We retraced this route on the way out.

Observer Comments

A wind deposited feature was identified as likely unstable based on prior observations that day. The slide was triggered by walking/trenching into the feature at which point it released above the 'tester'. The resulting slide was larger than anticipated. The 'tester' was carried down the slope some 20-30'.
