We travelled from Skyline towards Tye Peak, and headed back via Stormies. We stayed on smaller terrain, as steep test slopes aside from windward ones nearly all slid with soft slabs running at the interface beneath the last 24 hours' snow. About 20cm of F snow (new snow) was sitting over 7cm of 4F snow, which was well bonded to the 3/18 MFcr. This was on east aspects, where the 3/18 crust was around 5cm thick at 4500ft. On north aspects, 35cm was sitting on top of the 3/18 crust. As we returned midday, eastern terrain which had warmed up a bit had already become less reactive. Before reaching the PCT on our return, at about 4300ft, snow was becoming moist and rollerballing.
