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
Nescopeck Mountain flows through this valley. The valley is long and wide. Some streams on the ridge are part of the Lehigh River watershed. A stream known as Scotch Run flows through a valley with Nescopeck Mountain on its northern edge. Nescopeck Mountain forms a water gap with Catawissa Mountain. Catawissa Creek cuts through this water gap. There is also a water gap carved by Nescopeck Creek through Nescopeck Mountain. Both of these water gaps are relatively narrow. The mountain serves as part of the dividing line between the Susquehanna River and the Lehigh River watersheds. For some distance, the ridge runs
