We remotely triggered two SS-ASr-2-O persistent slab avalanches today on steep north facing slopes at 9600' from along the top of the West Deso ridgeline. You can find them here and here.

I've spent a fair bit of time on the north side of BCC and have found the weak Oct and Nov...and to some degree the faceted Christmas storm to be a near blend of facets and depth hoar. The crowns ranged from 1-2' deep and up to 300' wide and broke generally on fist hard facets from early December; however the slab itself (below the most recent few inches of wind slab and decomposing/fragmented storm snow) was itself a slab of 4f-1f rounding facets. Profile in avalanche obs linked above.

Interesting to note that only one of four ECTs in representative (perhaps more wind drifted) terrain prior to the remotely triggered slides elicited full propagation...again a note about tests being only a tool in the toolbox and conservatively weighing the lone "unstable" result over the others; particularly knowing the structure and general conditions.
