Back Creek is a tributary of the Potomac River that flows north from Frederick County, Virginia, to Berkeley County in West Virginia's Eastern Panhandle. Back Creek originates along Frederick County's border with Hampshire County, West Virginia, at Farmer's Gap in the Great North Mountain. Its name reflects its location to the west of North Mountain. The perspective of colonists from the east in the 18th century led them to call it "Back Creek", because it lay to the back of North Mountain. Course Source to Gore Back Creek's headwaters rise at Farmer's Gap in Great North Mountain. From its source, the creek flows northwest along the western edge of Burnt Ridge off the mountain. It turns toward the northeast, and the shallow stream flows along the western flanks of Great North Mountain, with White Pine Ridge bounding it to its west. Back Creek is joined by a series of mountain streams, including Reed Creek and Lauren Run, both flowing off Great North Mountain. At Dunlap Ford, Back Creek is joined to its west by waters from Gallows Ridge and to its east by those from Cove Ridge. There, it is also joined by Laurel Run, which carries the spring waters from Rock Enon Springs from the east. Capper Ridge bounds Back Creek to its west at Pooles Ford as it makes its way towards Gore, Virginia. This region on the western flanks of Great North Mountain is rich in sandstone and sand deposits, hence the sand mines at Gore. At Gore, Back Creek is joined by Mine Spring and Dry runs. Gore to De Haven From Gore, Back Creek flows parallel to the south of the Northwestern Turnpike (U.S. Route 50) and the Winchester and Western Railroad. It flows under US 50 along Bowling Green Ridge where it turns east towards Gainesboro, the site of its confluence with Tavenner Run. From Gainesboro, Back Creek flows beneath the North Frederick Pike (U.S. Route 522). At Grave Hill, north of Lew, Back Creek is joined by its two major tributaries: Isaacs Creek and Hogue Creek. From its fork with Hogue Creek, the stream is bounded by Hunting Ridge to its east. By its confluence with Brush Creek at Baileys Ford, Back Creek is a large stream with increased water flow with depths up to a few feet. Back Creek meanders northward through the community of De Haven at Warm Springs Ford. Shortly
