Another good dump overnight and this morning with 35cm new on Sproatt. With some clearing it was evident that almost all sudden convexities had run on E through NW asp during last night's storm at TL. Some crowns and flanks to 70cm est in non-rideable terrain.
Trailbreaking to ALP went from 20cm near valley to 35 at TL. At treeline and above deep soft alabs made for more difficult trailbreaking. Some whumpfing and cracking began immediately at TL.
Sluffs running on anything 35 deg or steeper. Ski pen ridiculous with cold dry smoke. Still some open creeks so not all gullies completely good to go, but awesome touring from the back door!
