Devonian Rock Beside the Route 26 Ramp

An exposure of the Devonian Brallier Formation, cut open where the ramp carries traffic from Route 22 west onto Route 26 north, facing roughly north-east. The thick blocky beds are sandstone and the layers between them are shale. It was photographed at the 82nd Annual Field Conference of Pennsylvania Geologists. The road cut is signed for Huntingdon; the rock itself is in Henderson township.
