81° on Nov. 11, 2020, the hottest reading for this week of the year since 1996. Next is 79° in 2011.
Keyser’s center stands about 920 ft above sea level. Within three miles the land runs from 770 ft to 2,440 ft, a difference of 1,670 ft: steep hill country. The highest named summit within 15 miles is Wild Turkey Rock, about 3,230 ft, 15 miles west.
The section below crosses 18 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.
Limestone, shale, sandstone. Age: Silurian, 422 to 445 million years old. About 4 mi of the line.
Shale, sandstone. Age: Devonian, 359 to 422 million years old. About 3 mi of the line.
Siltstone, sandstone. Age: Devonian, 359 to 422 million years old. About 3 mi of the line.
Fine-detrital, coarse-detrital. Age: Quaternary, less than 2.6 million years old. About 2 mi of the line.
Sandstone. Age: Carboniferous, 324 to 359 million years old. About 2 mi of the line.
Sandstone. 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. 12 smaller units along the line are not listed.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Keyser reaches Chesapeake Bay and the Atlantic Ocean by way of the North Branch Potomac and the Potomac: about 340 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Keyser; river miles along the main stem, rounded.
Keyser has a hot-summer humid continental climate. Summer afternoons average 89° in July; winter nights fall to about 21° in January. A normal year brings about 34 inches of snow; with the rain, that comes to about 41 inches of water.
Normals 1991–2020 and records since 1996 at Keyser 2 SSW, here. NOAA, through RCC-ACIS.
