Comments:
Hand check at put in 5900. Weather sun/blubird, 28F, Vis infinite. Distinct rain/humid crust, 3cm. Shear at 15cm. Humid, buoyant, high cohesion. Nice turns to 5000, distinct humidity and consolidation/runout lumpy. Snow continuous to 4500/Summit coverage good. Nice base layer, but the rain crust could be problematic relative to temperature/deposition.
