Mark Staples of the Gallatin National Forest Avalanche Center conducts an Extended Column Test in the northern Bridger Range. The snowpack is just over 5 ft deep, but this is shallow for this time of year given the recent storms. The isolated column pops off and propagates a fracture after 20 taps. They did not ski the slope.
Excellent advice! Especially now that the controlled areas are closing down.
DIG DOWN TO THE GROUND.

Thanks for the location info. I also found this faceted weak layer in a pit I dug on some low-angled meadows (NE facing) below Naya Nuki peak on 3/30 before the recent added snowpack.
