The Midlothian plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
73° on Nov. 15, 1993, the hottest reading for this week of the year since 1972. Next is 73° in 2020.
Midlothian’s center stands about 1,940 ft above sea level. Within three miles the land runs from 1,740 ft to 2,910 ft, a difference of 1,170 ft: steep hill country. The highest named summit within 15 miles is Zehner Hill, about 3,010 ft, 15 miles west-northwest.
The section below crosses 13 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.
Shale, siltstone. Age: Devonian to Late Devonian, 374 to 422 million years old. About 5 mi of the line.
Claystone, shale. Age: Carboniferous, 299 to 324 million years old. About 4 mi of the line.
Claystone, limestone. Age: Carboniferous, 299 to 324 million years old. About 3 mi of the line.
Sandstone, shale. Age: Carboniferous, 299 to 324 million years old. About 3 mi of the line.
Shale, sandstone. Age: Devonian, 359 to 422 million years old. About 3 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. 7 smaller units along the line are not listed.

A raindrop that lands in Midlothian reaches Chesapeake Bay and the Atlantic Ocean by way of Winebrenner Run, Georges Creek, the North Branch Potomac and the Potomac: about 360 river miles.
290 miles of the trip are on the Potomac.

Midlothian 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 Midlothian 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.
