Brandy Station’s center stands about 360 ft above sea level. Within three miles the land runs from 280 ft to 490 ft, a difference of 210 ft: rolling country. The highest named summit within 15 miles is Battle Mountain, about 1,160 ft, 14 miles northwest.
The section below crosses 15 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 43×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Melange. Age: Neoproterozoic to Ordovician, 445 to 1,000 million years old. About 5 mi of the line.
Shale, siltstone. Age: Triassic, 202 to 252 million years old. About 3 mi of the line.
Basalt. Age: Early Jurassic, 175 to 202 million years old. About 3 mi of the line.
Metabasalt. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 2 mi of the line.
Metagraywacke. Age: Neoproterozoic, 542 to 1,000 million years old. About 2 mi of the line.
Granulite, gneiss. 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. 9 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 Brandy Station reaches Chesapeake Bay and the Atlantic Ocean by way of Flat Run, Mountain Run and the Rappahannock: about 150 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Brandy Station; river miles along the main stem, rounded.
