The Skunnemunk Conglomerate is a mapped bedrock unit in New Jersey and New York from the Middle Devonian period.[1] It forms the resistant ridge of Schunemunk Mountain in New York and Bearfort Mountain in New Jersey.[2]

Description

The Skunnemunk is a Middle Devonian, grayish-purple to grayish-red, thin to very thick-bedded, locally cross–bedded, conglomerate and sandstone containing clasts of white vein quartz, red and green quartzite and sandstone, red and gray chert, and red shale.[1] It is a classic Puddingstone. Pieces of the conglomerate are easy to recognize and have been found in glacial deposits throughout the lower Hudson Valley region.[2]
