Avalanche: Hatcher Pass

Location: Upper Jim Creek, Frontier Peak

Route & General Observations

Large Avalanche came down from South-west gully on frontier. Debris pile is a mile long. The rippey trail is pretty dry and excellent for jogging and mountain biking if you are eager. The avalanche debris is only 1/4 mile off trail and well worth checking out. Alpha angle measured at 27 degrees, meaning an avalanche could easily cross this trail. We encountered excellent corn skiing up high on south and southwest aspects.
