Harvey Conglomerate Sandstone

From West Virginia (WV) Cyclopedia

The Harvey Conglomerate Sandstone reaches 50 feet in thickness and forms a "very pronounced ledge" in the New River Gorge region about 50-to-100 feet below the base of the prominent Nuttall Sandstone, according to the West Virginia Geological Survey. The conglomerate forms cliffs of 50-to-75 feet in height along the lower New River from Keeneys Creek to the river's mouth at Gauley Bridge, WV. The rock is described as similar to that of the lower Nuttall Sandstone, though less siliceous. The conglomerate takes its name from Harvey (now Bolt) in Raleigh County, rather than Harvey in Fayette County.
