Pine Creek Canyon

Pennsylvania Geological Attractions and Destinations


Pine Creek Canyon, "Pennsylvania's Grand Canyon," is showcased in the adjoining Leonard Harrison and Colton Point State Parks in the northern Allegheny Plateau. The plateau, topped by Carboniferous conglomerate, is deeply dissected by Pine Creek down into Devonian strata. Ice Age dams to the north forced Pine Creek to run south instead of north, creating a natural boulevard through the uplands later occupied by rail lines.
