Friendsville’s center stands about 1,520 ft above sea level. Within three miles the land runs from 1,430 ft to 2,620 ft, a difference of 1,190 ft: steep hill country. The highest named summit within 15 miles is Mount Davis, about 3,220 ft, 15 miles northeast.
The section below crosses 9 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 12×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Claystone, shale. Age: Carboniferous, 299 to 324 million years old. About 8 mi of the line.
Sandstone. Age: Carboniferous, 299 to 324 million years old. About 5 mi of the line.
Sandstone. Age: Carboniferous, 324 to 359 million years old. About 4 mi of the line.
Sandstone, shale. Age: Carboniferous, 299 to 324 million years old. About 3 mi of the line.
Shale. Age: Carboniferous, 299 to 324 million years old. About 2 mi of the line.
Shale, sandstone. Age: Devonian, 359 to 422 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. 3 smaller units along the line are not listed.

A raindrop that lands in Friendsville reaches the Gulf of America by way of Bear Creek, the Youghiogheny, the Monongahela, the Ohio and the Mississippi: about 2,050 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 Friendsville; river miles along the main stem, rounded.
Friendsville has a hot-summer humid continental climate. Summer afternoons average 84° in July; winter nights fall to about 19° in January. A normal year brings about 61 inches of snow; with the rain, that comes to about 47 inches of water.
On November 14 Friendsville normally reaches 52° and falls to 30°. The record high is 74°, in 1989; the record low 7°, in 1986. The most rain on this date, 0.90 in, fell in 1972.
Normals 1991–2020 and records since 1946 at Confluence 1 SW Dam, 10 miles north-northeast. NOAA, through RCC-ACIS.
