Intense band of snowfall this morning, followed by a midday lull in activity. I was out in the afternoon/evening, checking on the storm in progress. It snowed a relatively steady S-1 to S1 throughout tour, accumulating an additional cm. Winds were generally calm to light out of the S, with occasional periods of a bit stronger, moderate wind.
I observed one new wind slab avalanche along the roadway between Stanley and the Stanley Ranger Station that appeared to have been triggered by elk.
My primary goal was to see what the storm was doing and to check in on the persistent slab problem in this area. I dug two pits on a W aspects and found a 40+cm thick slab overlying the 2/18 weak layer, which presented as a stack of impressively weak (F--), large-grained (up to 2.5mm), well-developed facets. This layer produced repeated ECTPs with light force, including an ECTPV. It also produced some large collapses both before and after I dug. The slab graded somewhat evenly from F to 4F+ at the base.
Persistent weak layers in the upper snowpack have caused me to gradually step back as the slab on top of them is built.
