Halcott Mountain is a broad, mostly forested Catskill High Peak in New York on the divide between the Hudson and Delaware watersheds, with steep eastern slopes into Deep Notch and gentler western slopes toward Elk Creek. Part of an eroded plateau rather than a sharply uplifted range, it was shaped by ancient shale and sandstone, later glaciation, and ongoing erosion. Mature northern hardwood forest covers most of the mountain, though some first-growth remains near the summit and traces of past farming and hemlock cutting survive. Protected within New York’s Forest Preserve, Halcott is now a trailless but popular hiking objective in the Catskill Park.
