Pulpit Rocks, National Historic Landmark in Huntingdon County, Pennsylvania, United States
Pulpit Rocks are sandstone formations along Warrior Ridge that rise approximately 50 feet (15 meters) high and are separated by gaps wide enough to walk through. The structures display distinct layers of different rock types stacked vertically, creating a natural geological display.
These formations were studied by the Pennsylvania Geological Survey in the 1850s and provided crucial evidence for understanding how the Appalachian Mountains were structured in layers. The discovery of alternating rock types challenged existing scientific theories about mountain formation in North America.
Juniata College geology department conducts regular field studies at Pulpit Rocks, contributing to earth science education in Pennsylvania.
The site is accessible from Pike Road, located northwest of Huntingdon, and remains open throughout the year for visitors. The sandy and rocky ground can become slippery after rain, so sturdy footwear is recommended when navigating between the formations.
The rock formations display an unexpected pattern of alternating sandstone and other rock layers that surprised 19th-century scientists. This layering pattern was one of the first clear examples demonstrating the complex internal structure of the Appalachian Mountains.
