Thin Crust

Mellow day with pleasant weather, mild wind. Dug a pit on SE aspect, 2100m. HS 150cm. Storm slab (becoming wind affected) failed CTE4 on last weeks' sun crust. 20cm depth. ECT showed no results in terms of stepping down or propagating. There is a really thin zipper crust just below 2-3cm of storm pow but riding quality is still good.
