Snow cornice even being on the snow on top of rock exposes the alpinist to hazard in this situation. The best practice in mountaineering is to stay far enough back from the edge so as not to be able to see the drop, as an approximate metric of exposure. In avalanche safety, cornices are a high avalanche danger as they often break and trigger larger avalanches that permeate several snow layers. Cornices are particularly vulnerable to collapse during periods of solar warming. Snow cornice A snow cornice or simply cornice (from the Italian cornice meaning "ledge") is an overhanging edge of snow
Sourland Mountain Strawberry Hill. A knob in the shallow valley between Strawberry Hill and the southernmost stretch of the main ridge forms Belle Mountain. Goat Hill comprises the highest point of the main ridge before reaching the southernmost end of Sourland Mountain at the Delaware River. Partly adjacent to Sourland Mountain is a sizeable traprock ridge which extends eastward from Pennington Mountain for approximately nine miles, forming (from west to east) Mount Rose, Rocky Hill, and Ten Mile Run Mountain. West of the main ridge, near Flemington, is Prospect Hill, a volcanic remnant lying along the western edge of the Amwell Valley.
