Formation

Rock shelters form because a relatively resistant rock stratum such as sandstone has formed a cliff or bluff, while a softer stratum like shale lies just below and is worn away by erosion (from water flows or wind) and weathering (especially that of frost). Rock shelters can be found behind waterfalls and are typically modest in size compared to deeper formations like solutional caves.
