Headed up Peters Ridge at an ambitiously alpine 11am. Even the untracked snow on the sides of the road was so supportable to render the scratchers useless. We did observe some small surface hoar development in the open zone at the trailhead, but didn't find more, even in open areas, as we ascended. Skied a south aspect on a very supportable crust, which skied better than expected as long as we avoided old tree-bomb debris. Untouched surface snow was pencil-hard 5cm crust over drier, fist-hard snow. We saw many many old and frozen rollerballs, point releases, and treebombs from prior days, which were knife (maybe chainsaw) hard. The snow below 5000' was softening by afternoon, and was moist and melting below 4000'.
