Flathead Avalanche Center

Poor snowpack structure. Good stability.

Holiday storm (12/27 to 1/4) from 152 to 65 cm.

12/28 interface (SH/ NSFs) at 95 cm. 11/29 Drought FC interface down 150 cm from the surface at 42 cm (below graphed pit - but we dug down to confirm). The drought FC layer is rounding in this snowpit/ slope location.

Snowpit dug adjacent to a natural avalanche from December 8, 2022. The avalanche and today's tests failed in the same weak layer, 2-4 mm DH/ FC (4F-).
