Heritage Geology of Pennsylvania

Heritage geologic features are recognized special places of intertwined geology and landscape. Heritage geologic features may include unique or exemplary outcrops, scenic views, or other geologically significant features that together represent the geologic diversity of the Commonwealth. Such features may be classified into different types that may be enjoyed, studied, and appreciated by all. The Department of Conservation and Natural Resources, Pennsylvania Geological Survey, is striving to promote the awareness, appreciation, and conservation of such outstanding
geologic features by documenting their presence.

PNHP also works in cooperation with the Pennsylvania Game Commission, the U.S. Fish and Wildlife Service, and the Pennsylvania Fish and Boat Commission.
