Southampton’s center stands about 1,820 ft above sea level. Within three miles the land runs from 1,200 ft to 2,660 ft, a difference of 1,460 ft: steep hill country. The highest named summit within 15 miles is Sampson Rock, about 2,940 ft, 7 miles southwest.
Under the town center the state geologic map shows Casselman Formation (shale, clastic), from the Carboniferous, 299 to 324 million years old.
The section below crosses 17 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 8×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sandstone. Age: Late Devonian, 359 to 384 million years old. About 4 mi of the line.
Sandstone, siltstone, shale. Age: Late Devonian, 359 to 384 million years old. About 3 mi of the line.
Sandstone. Age: Carboniferous, 299 to 324 million years old. About 3 mi of the line.
Shale, siltstone. Age: Devonian to Late Devonian, 374 to 422 million years old. About 2 mi of the line.
Shale, clastic. Age: Carboniferous, 299 to 324 million years old. About 2 mi of the line.
Shale. Age: Devonian, 359 to 422 million years old. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 11 smaller units along the line are not listed.

A raindrop that lands in Southampton reaches Chesapeake Bay and the Atlantic Ocean by way of Gladdens Run, Wills Creek, the North Branch Potomac and the Potomac: about 330 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Southampton; river miles along the main stem, rounded.
Southampton has a warm-summer humid continental climate. Summer afternoons average 80° in July; winter nights fall to about 19° in January. A normal year brings about 72 inches of snow; with the rain, that comes to about 45 inches of water.
On November 14 Southampton normally reaches 49° and falls to 32°. The record high is 64°, in 2005; the record low 8°, in 1986. The most rain on this date, 0.69 in, fell in 1972.
Normals 1991–2020 and records since 1972 at Frostburg 2, 9 miles southwest, 350 ft higher. NOAA, through RCC-ACIS.
