Geology

Mackeyville is located in the Ridge and Valley system. Locally the town and surrounding areas rest on the Bellefonte Formation, the springs in the area being attributed to the resulting karst topography. This is due to that Bellefonte Formation being a predominately acarbonate rock. Several exposures maybe found along the streams and a rock cuts along Mackeyville Rd and Duck Run Rd.^[8]
