Brothersvalley’s center stands about 2,210 ft above sea level. Within three miles the land runs from 2,010 ft to 2,540 ft, a difference of 530 ft: hilly country. The highest named summit within 15 miles is Mount Davis, about 3,220 ft, 13 miles southwest.
The section below crosses 8 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 13×. 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: Carboniferous, 299 to 324 million years old. About 8 mi of the line.
Shale. Age: Carboniferous, 299 to 324 million years old. About 5 mi of the line.
Sandstone. Age: Late Devonian, 359 to 384 million years old. About 4 mi of the line.
Shale, clastic. Age: Carboniferous, 299 to 324 million years old. About 3 mi of the line.
Sandstone, siltstone, shale. Age: Late Devonian, 359 to 384 million years old. About 3 mi of the line.
Sandstone, conglomerate. Age: Carboniferous, 299 to 324 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. 2 smaller units along the line are not listed.

A raindrop that lands in Brothersvalley reaches the Gulf of America by way of Buffalo Creek, the Casselman, the Youghiogheny, the Monongahela, the Ohio and the Mississippi: about 2,070 river miles.
970 miles of the trip are on the Ohio.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Brothersvalley; river miles along the main stem, rounded.
Brothersvalley 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 Brothersvalley 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, 17 miles south. NOAA, through RCC-ACIS.
