Silver Creek Trail/French Cabin Mountain (west peak)
Did you trigger any avalanches?
Was it intentional?
Size 1: Relatively harmless to people
Triggered small superficial wind slab breaks when going up/down south face. The slabs were approximately 1/16" thick.
Signs of Unstable Snow
Hiking up Kachess Ridge Trail using Domerie Divide Trailhead. A lot of the snow below treeline prior to the Little Kachess Ridge junction had melted by the time I got back (was <1"). The snow in the Silver Creek Basin along the trail was <6" deep, with it being closer to 6" in open areas, i.e., not under tree cover.
Getting closer to Silver Creek Tie Trail and hiking along it, I found pockets of windswept powder between 6" and 30" deep; the 30" deep powder was when I came down a mini-col along the S summit ridge. Even though I went up the dry rock due to avalanche concern, I went down the mini-col due to exposure concern dealing with poor, steep rock (scree in areas); I quickly transitioned back to the rock and crab walked down it once I hit the deep undisturbed windswept/dry powder.
Conditions were mostly sunny transitioning to clear until dusk; after dusk, sky was obscured slightly.
Observed Avalanche Problem #1:
Wind slabs were observed on S faces. I believe the fetch was blown over the hill to the N/E faces, given that the S face was lower (except in leeward areas). Cornices have not yet formed, but they were starting to overhang to the N/NE.
Observed Avalanche Problem #2:
Noticed dry loose transitioning to wet loose near treeline on S facing slopes due to solar input.
Observed Avalanche Problem #3:
Noticed some superficial sluffing when walking along the slopes below treeline coming out of Silver Creek Basin and near treeline along Silver Creek Tie Trail.
