This large natural avalanche occurred just outside the northern boundary of Big Sky Resort. It broke close to one thousand feet wide was triggered by a natural cornice fall. The slide occurred on a NE facing slope and failed on the facet layer formed during the January dry spell. It stepped down and broke on facets near the ground on the far right side of the slide.

GNFAC Avalanche Advisory for Mon Mar 3, 2014
Cooke City
The mountains around Cooke City have a lot of snow. At Fisher Creek Snotel site (elev. 9,100 ft.) there is ten feet of snow on the ground. Higher elevations have even more snow. A general rule of thumb is that a deep snowpack is a strong snowpack. However, relentless snowfall and strong winds continue to produce multiple avalanche problems (video).
