Rock shelter

A rock shelter (also known as a rockhouse, crepuscular cave, or abri) is a shallow cave-like opening at the base of a bluff or cliff.

Rock shelter

Rock shelters form because a rock stratum such as sandstone that is resistant to erosion and weathering has formed a cliff or bluff, but a softer stratum, more subject to erosion and weathering, lies just below the resistant stratum, and thus undercuts the cliff.

Many rock shelters are found under waterfalls.

Rock shelters are often important archaeologically. Because rock shelters form natural shelters from the weather, prehistoric humans often used them as living-places, and left behind debris, tools, and other artifacts. In mountainous areas the shelters can also be important for mountaineers. In western Connecticut and eastern New York, many rock shelters are known by the colloquialism "leatherman caves"[1], as they were inhabited by the Leatherman over three decades in the late 1800s.
