Skiing any slopes above 35 degrees triggered (manageable) wet loose slides today in the Heather-Maple Pass area. Highly reactive ~5" of loose wet snow on top of previously consolidated base. The rain has done a number on the snow pack leaving lots of moisture in its upper layer. None of the slides stepped down into older layers, however, and we were able to successfully manage fall lines throughout the day.
We attempted Corteo Peak, but overhanging cornices above its SW ridge access gullies turned us around. After hoping clouds would lift to get an eye on Black's NE ridge, we skied the Lewis Glacier and then skinned back to Heather Pass - across a hang fire zone from dropping county line cornices to the east of Horsefly Pass. A probe check on top of Heather Pass revealed a 200cm snowpack base - crazy for June! We elected to ski the south aspect directly to Lake Ann and skin out the summer lake trail as opposed to the descending traverse loosely following the Heather Pass trail - figuring we'd be cutting loose untold numbers of loose wet slides above tbd snowshoers below. The south aspect felt more stable than the north and northeast slopes on the backside of Heather Pass and only produced some small sluff.
A classic Cascade spring pollen/pine/dirt exit through the trees back to Hwy 20. Pollen wasn't as bad as expected though.
