Summary:

Buffalo Mountain paleosol is very representative of a typical paleosol in the Duncannon Member of the Catskill Formation. The Duncannon exhibits repeated stacking of 5- to 10-m thick fining-upward sequences that consist of erosive-based, non-red, cross-stratified, medium- to coarse-grained channel sandstone; red-brown, ripple cross-laminated to parallel-laminated, very fine- to fine-grained sandstone; red-gray silty claystone, commonly with paleosol features. The 5-m thickness of the paleosol interval suggests that it probably is composed of several different paleosols, formed by repeated episodes of floodplain aggradation alternating with pedogenesis. Rhizoliths and calcareous nodules occur just above the laminated siltstone at the base of the Buffalo Mountain, indicating rooting during early stages of soil formation. Above the nodules are 3 m of clayshale, characterized by pedogenic slickensides. Age of the Duncannon and its Buffalo Mountain paleosol is Late Devonian.
