Rocky Gap’s center stands about 2,020 ft above sea level. Within three miles the land runs from 1,990 ft to 3,500 ft, a difference of 1,510 ft: steep hill country. The highest named summit within 15 miles is Sugar Run Mountain, about 4,090 ft, 14 miles east.
The section below crosses 15 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 9×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Age: Ordovician to Silurian, 422 to 487 million years old. About 6 mi of the line.
Shale, sandstone. Age: Carboniferous, 324 to 359 million years old. About 3 mi of the line.
Black-shale. Age: Devonian, 359 to 422 million years old. About 3 mi of the line.
Sandstone, limestone, shale. Age: Silurian to Devonian, 359 to 445 million years old. About 3 mi of the line.
Shale. Age: Ordovician, 445 to 487 million years old. About 1 mi of the line.
Dolostone, limestone. Age: Cambrian to Ordovician, 445 to 542 million years old. About 1 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 9 smaller units along the line are not listed.

A raindrop that lands in Rocky Gap reaches the Gulf of America by way of Laurel Creek, Wolf Creek, the New River, the Kanawha, the Ohio and the Mississippi: about 1,900 river miles.
970 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Rocky Gap; river miles along the main stem, rounded.
Rocky Gap has a warm-summer humid continental climate. Summer afternoons average 79° in July; winter nights fall to about 24° in January. A normal year brings about 35 inches of snow; with the rain, that comes to about 41 inches of water.
On November 14 Rocky Gap normally reaches 53° and falls to 35°. The record high is 81°, in 1993; the record low 8°, in 1986. The most rain on this date, 0.97 in, fell in 2024.
Normals 1991–2020 and records since 1909 from the Bluefield Area threaded record (Bluefield Mercer County Airport, 7 miles northwest, 840 ft higher). NOAA, through RCC-ACIS.
