Route & General Observations

Toured from Prospect TH towards Rusty Point. Up through the tree and alders towards the north flank. Above tree line, but still in alders, around 2000ft started seeing and hearing all the red flags in this area! Dug a quick pit to confirm and see what we were experiencing. See pit details. Kept the day lower than planned and enjoyed low angle skiing in 20-30cm of new light snow.

Weather

Mostly blue sky day and minimal to no wind during our tour. 18 degrees leaving the lot at 11:30am. 23 at return.

Snow surface

20-30cm of new, light snow from the last two storms. Some mild signs of wind transport between the storms, but not much since the last 6 inches.

Snowpack

Upon seeing and feeling the red flags, we quickly dig a pit to confirm what we were experiencing.
At this location: 2350ft, N aspect, 23degree slope.
Snow height about 80cm.
At the moment we cut the ECT loose from the surrounding snow, the entire block failed at the ground! ECTPV. Never even got the shovel to it! Still did some taps on the column and also got an ECTP 3 at 30cm down on the new snow/wind-sun crust that was there before the new snow.
