Cannonsville Reservoir dominates the southern reaches of this landscape, its waters contained within the City of New York Water Supply Reservation Boundary. The reservoir's presence fundamentally altered the valley of the East Branch, marking a significant era of water infrastructure development in Delaware County. To the north, the terrain transitions into the dense woodlands of the Delaware State Forest, where numerous hollows such as Mormon Hollow and Sherruck Hollow define the drainage patterns leading toward the West Branch Delaware River watershed.
