The Catskill Formation

The Catskill Formation is a geological layer primarily composed of sandstone, shale, and some conglomerates, formed during the Devonian period around 370 million years ago. It represents ancient river and delta environments that deposited sediments in what is now the northeastern United States, especially in the Catskill Mountains of New York. Over millions of years, these sediments were compacted and turned into rock. Today, the Catskill Formation is important for its fossil records, natural resources, and scenic landscapes, showcasing the area's ancient river systems and sedimentation processes that contributed to the region's geology.
