Quick report
We traveled around the ten lakes area to check on the recent snowfall and assess buried weak layers.
- We found an incredible amount of recent snow (6 to 8 inches overnight, 1.5 to 2.5 feet since 2/17).
- We saw recent natural sluffing in the new snow as well as several slab avalanches that likely occurred during the 2/17 snowfall.
- We got mixed results with hard force on the buried surface hoar down ~2 feet.
We recognized that given the amount of recent snow, even small slopes could produce large avalanches. We gave all steep slopes a wide berth and enjoyed faceshots on low-angle and even flat terrain.
Sleds pushed sluffs around on most slopes. No collapsing during our short walks.
