Observer Comments

Observed one new avalanche at the head of Ingram Creek drainage between Eddie's and Tincan/Kickstep ridges on the headwall between Kickstep and Pt 3720. Viewed from several miles away so details are very rough. W aspect 3,500'. D2 maybe cornice triggered. (see photo)

Snow surface

1,000-2,000’ - diurnal melt freeze cycle continuing today. Surface beginning to soften by 10:30am, ski penetration 6” upon descent at 6pm
2,000-3,000’ - settled powder and wind scalloped surfaces. Some areas scoured down to pre-St Patty’s storm melt freeze/wind affected surfaces
Roller balls released on steep S facing slopes in the early to mid afternoon
A few larger wet loose avalanches in steep terrain on Big Chief noted- large enough to knock a person over and/or cause injury.


We dug twice in Warm Up Bowl and found bonding between the St patty’s day slab and the old crust to be very good. No test results worth noting. We looked in locations that could have been previously sheltered and maybe held faceted snow prior to the St Patty’s day loading event. There was no sign of this layer in these 2 pits. Generally stable snow was found where we looked today.

Pit 1 - NW - 2,200 - 40cm slab
Pit 2 - NW - 2,400 - 65cm slab
