POPOLOPEN MOUNTAIN AND GORGE
Bear Mountain, New York
Exfoliation accounts partly for the rounding of many summits in the highlands. One example is on Popolopen Torne.
Crescentic gouges that occur when rock fragments embedded in Pleistocene glacier ice move over a bedrock surface fracturing the bedrock to a depth of several inches are abundant on Popolopen Torne's north side. They are convex toward the southeast, the direction of ice movement. Irregularities and grouping here are typical. (Wyckoff 1971:71)
Potholes and plunge basins have been eroded out by the swirling water of Popolopen Brook just above "Hell Hole." (Wyckoff 1971:43)
