Bottom Line

Toured up G- spot, dug a pit near the top at 6,200 feet. The two to three inches of fresh that sits over a 6-inch thick rain crust had little wind effect in this area. The layers below show signs of previous moisture down to approximately 24 inches (60 cm). Layers of facets and crust exist below the thick rain crust. The snowpack is hard and well-rounded below 30 inches (75 cm). Our primary concern is the thick rain crust will provide a slick bed surface for avalanches to run on when we get the next load.
