Yes
Avalanche Type:
Soft Slab
Size:
Size 1: Relatively harmless to people
Elevation:
NTL
Aspect:
NW
Comments:
Observed multiple human-triggered windslabs on our tour around Table. We spoke to a party who triggered a slab which appeared to have propagated above them (size 1.5 W aspect ran onto common "upper" circumnavigation route). The attached image is of a small natural release below Ptarmigan ridge.

Signs of Unstable Snow

None reported

Observations

Traveled through Herman saddle to Iceberg lake and around Table, dropping BTL before climbing to Ptarmigan bowl and to Artist's pt.

We dug a hand pit to a hard crust layer ~1 ft down on NW slope on the corner of Table mtn (below Pond shot). Easy results with the slab breaking 4-6" deep. About 6" below the snow surface we found a thin crust with weak snow around the crust and 4" of denser wind slab above.
