Rock shelters form because a relatively resistant rockstratum such assandstone has formed acliff or bluff, while a softer stratum likeshale lies just below and is worn away byerosion (fromwater flows orwind) andweathering (especially that offrost).[1][2] Rock shelters can be found behindwaterfalls[3] and are typically modest in size compared to deeper formations likesolutional caves.[1]

Rock shelters are often importantarchaeologically.[1] Because rock shelters form natural shelters from the weather, prehistoric humans often used them as living places, leaving behind debris, tools, and otherartifacts. Rock shelters in montane areas can be of use tomountaineers.[4]

In westernConnecticut and easternNew York, many rock shelters are known by thecolloquialism "leatherman caves",[5] as they were inhabited by theLeatherman over three decades in the late 19th century.
