Wintergreen’s center stands about 2,920 ft above sea level. Within three miles the land runs from 720 ft to 3,620 ft, a difference of 2,900 ft: mountain country. The highest named summit within 15 miles is The Priest, about 4,060 ft, 9 miles southwest.
Under the town center the state geologic map shows Charnockite, from the Mesoproterozoic, 1 to 1.6 billion years old.
The section below crosses 11 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 6×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Quartzite, conglomerate, sandstone. Age: Cambrian, 487 to 542 million years old. About 8 mi of the line.
Biotite-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 3 mi of the line.
Granulite, gneiss. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 3 mi of the line.
Age: Mesoproterozoic, 1 to 1.6 billion years old. About 2 mi of the line.
Dolostone. Age: Cambrian, 487 to 542 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. 5 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 Wintergreen reaches Chesapeake Bay and the Atlantic Ocean by way of Little Stony Creek, Stony Creek, the Rockfish and the James: about 230 river miles.
200 miles of the trip are on the James.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Wintergreen; river miles along the main stem, rounded.
