Upperville’s center stands about 550 ft above sea level. Within three miles the land runs from 430 ft to 1,060 ft, a difference of 630 ft: hilly country. The highest named summit within 15 miles is High Knob, about 2,380 ft, 14 miles west-southwest.
Under the town center the state geologic map shows Layered Leucocratic Granite Gneiss, from the Mesoproterozoic, 1 to 1.6 billion years old.
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.
Gneiss. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 5 mi of the line.
Metabasalt. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 5 mi of the line.
Metagranite. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 4 mi of the line.
Biotite-gneiss. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 3 mi of the line.
Leucocratic-granitic. Age: Mesoproterozoic, 1.1 to 1.1 billion years old. About 2 mi of the line.
Metagranite. Age: Mesoproterozoic, 1 to 1.6 billion 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. 3 smaller units along the line are not listed.

A raindrop that lands in Upperville reaches Chesapeake Bay and the Atlantic Ocean by way of Panther Skin Creek, Goose Creek and the Potomac: about 180 river miles.
150 miles of the trip are on the Potomac.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Upperville; river miles along the main stem, rounded.
