We triggered shooting cracks on a small, south-facing slope near Astral Lake, north of Cooke City. The cracks went down to a layer of surface hoar and facets on a crust. Photo: GNFAC

Cooke City, 2021-01-18

From obs: "While skinning up the south shoulder of Scotch Bonnet [on 1/15/21], about half way (~10,000 ft.) shooting cracks occurred on convexities and were accompanied by whumpfing. While traversing a slope a crack shot perpendicular to the slope at a convexity about 60 ft. up and the whole slope collapsed. After this we immediately turned around taking the most conservative path. These conditions were not present lower down the slope and a snow pit showed no propagation with only a Q3 fracture on the recent layer of surface hoar..." Photo: M. Dvorsak

From email: "Extremely touchy snowpack in the pebble creek drainage [on 1/16/21]. Nearly constant collapsing and cracks were shooting very long distances. Snowpack was definitely sending a clear message!" Photo: J. Zimmerer
