Approached Mt. Sproatt from the East hiking trail. Skinnable snow started around 1,300m. In open terrain, any snow that wasn't packed down already or wind affected was glopping to our skins like crazy. Found lots of surface hoar at treeline and Alpine on several aspects, including North and southeast. The North slopes of Sproatt skied very nicely. Further down in the valley to the north, early season hazards such as cliffs and trees were abundant. The valley holds crusty and icy snow well into Twenty-one Mile Creek trail down to just below 1,000m.
