Colorado Avalanche Information Center

Winds protected areas have a P hard winds slab on top of the snowpack in this pit. This Winds Slab does not appear to be very reactive in other areas where I dug (in one place: ECTP25 @ 40 cm and about 100 ft distance: ECTN23 @ 15 below the surface - depends on WS thickness)

Lots of wind-loading during the holiday storm.
