Sideling Hill is a long, steep, narrow mountain ridge in the Ridge-and-Valley physiographic province of the Appalachian Mountains, located in Washington County in western Maryland and adjacent West Virginia and Pennsylvania, USA. The highest point on the ridge is Fisher Point, at 2,310 feet in Fulton County, Pennsylvania.
Sideling Hill is a syncline mountain, in a region of downward-folded rock strata between two upfolded anticlines. The ridge is capped by an erosion-resistant conglomerate and sandstone of Mississippian geologic age, the Purslane Sandstone of the Pocono Formation. The ridge's slopes are formed of much more easily eroded kinds of rock, including the Devonian-Mississippian Rockwell Formation, with long, narrow valleys paralleling the ridge on either side.
