Observation: Hatcher Pass

Location: Hatch Common

Route & General Observations

Mostly standard route to Hatch Common with a little foray into a West facing gully above summit lake to get near the base of April bowl. In this gully we experienced a shooting crack that triggered a very small+shallow wind slab (6’x2’x3″) about 15′ away. Obvious wind transport of surface snow in upper elevations. Cracking in wind drifted snow along ridgelines. Altered our intended terrain choices due to red flags.
Observed many instances of debris from point releases in steep terrain.
