Slab avalanche ran in a path known as Infinity on the south face of Snowflip Mountain sometime early this morning. Size D2 and ran about 3/4 distance down the path terminating above the rail grade. Unsure about the failure plane/weak layer? Might have just been a wind slab from recent loading or may have stepped down into a persistent weak layer deeper in the snowpack. No other avalanche activity observed.
Observations today were from the highway, so a fair amount of uncertainty regarding the avalanche. Looked like soft slab debris (more fine, not too chunky) so thinking just a wind slab from recent loading. Crown was starting to fill in, but at it thickest looked to be nearing 3+ feet thick. Our snowpack isn't very deep this season, so can't rule out that this failed on a deeper persistent weak layer.
