Inspired Summit Adventures owner and guide extraordinaire, snow-pro, and all around amazing human, Shaun Raskin demonstrates an extended column, snow stability test on an upper elevation shady slope in the western Uinta's. The results illustrate our reluctance to step out aimlessly into big terrain.
The good news is... the odds of triggering a slide on a persistent weak layer have decreased. Yeah, you'd really have to go out of your way to trigger a slide that breaks to older layers of snow today. However, fresh pow on a go-anywhere base, tends to steer us into bigger terrain, especially slopes in the wind zone.
The less than ideal news is... while so much of the range avalanched during the mid January storm cycle, a few slopes remain intact, just waiting for us to roll along, tickle the right spot, and collapse the snowpack, often around a rock or bush barely hidden under the snow. When it all comes together, it all comes apart and we'll be staring staring down a dangerous avalanche.
The flake news... if you choose to enter avalanche terrain and ride steep slopes, stack the odds in your favor. Avoid areas of thinner snow near rocks (sometimes hard to do), make sure the runout zone is free of trauma-inducing trees and rocks, and make sure your partners watch you from a safe area.
