Pamplin City’s center stands about 690 ft above sea level. Within three miles the land runs from 540 ft to 750 ft, a difference of 210 ft: rolling country. The highest named summit within 15 miles is Kyles Mountain, about 1,150 ft, 15 miles north.
Under the town center the state geologic map shows Interlayered Mafic and Felsic Metavolcanic Rocks - Foliated felsite, from the Cambrian, 487 to 542 million years old.
The section below crosses 8 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 33×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Metagraywacke, mica-schist. Age: Neoproterozoic to Cambrian, 487 to 1,000 million years old. About 7 mi of the line.
Granite, monzogranite. Age: Proterozoic, 542 to 2,500 million years old. About 5 mi of the line.
Metavolcanic. Age: Cambrian, 487 to 542 million years old. About 4 mi of the line.
Amphibolite, biotite-gneiss, schist. Age: Cambrian, 487 to 542 million years old. About 3 mi of the line.
Biotite-gneiss. Age: Cambrian, 487 to 542 million years old. About 3 mi of the line.
Mica-schist. Age: Neoproterozoic to Cambrian, 487 to 1,000 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. 2 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 Pamplin City reaches Chesapeake Bay and the Atlantic Ocean by way of Vaughans Creek, the Appomattox and the James: about 210 river miles.
Lake on the way: Lake Chesdin.
90 miles of the trip are on the Appomattox.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Pamplin City; river miles along the main stem, rounded.
