Avalanche: Hatcher Pass

Location: Gold Mint Trail, Mile 5-6

Route & General Observations

Two small D1 wind slab avalanches on cross loaded east facing slopes. Widespread cross loading on west facing slopes. Was very difficulty to tell wind slabs from sastrugi, as even some of the cross loaded gullies had some surface scouring from the wind. Lots of woomphing and shooting cracks on the flat.
