Kaaterskill Clove is a deep gorge, or valley, in New York's eastern Catskill Mountains, lying just west of the village of Palenville and in Haines Falls. The clove was formed by Kaaterskill Creek, a tributary of Catskill Creek rising west of North Mountain, and is estimated by geologists to be as much as 1 million years old. Kaaterskill High Peak and Roundtop Mountain rise to the north of the gorge, while South Mountain is to its south. This makes the gorge as deep as 2,500 feet in places.
