Prime Rib Rainbow.

Cold Clear temps. Light Northerly winds. Skid decent powder in sheltered areas @ above treeline and below. steep slope had little exposure to wind loading. Very dense slabs and major wind effect were found on mellow slopes along ridge on mellow ski runs. no avalanches observed in our ski area. East Face of Rainbow from our viewpoint looked wind scoured and old avalanche debris was seen at the bottom below the glacier.
