The Peachtree Corners 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.
Peachtree Corners’s center stands about 1,050 ft above sea level. Within three miles the land runs from 900 ft to 1,110 ft, a difference of 210 ft: rolling country. The highest named summit within 15 miles is Stone Mountain, about 1,670 ft, 12 miles south-southeast.
Under the town center the state geologic map shows Metagraywacke/ Mica Schist (metagraywacke, mica-schist), from the Precambrian to Paleozoic.
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 62×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Biotite-gneiss. Age: Precambrian to Paleozoic. About 7 mi of the line.
Schist. Age: Precambrian to Paleozoic. About 7 mi of the line.
Amphibolite, biotite-gneiss, mica-schist. Age: Precambrian to Paleozoic. About 6 mi of the line.
Metagraywacke, mica-schist. Age: Precambrian to Paleozoic. About 2 mi of the line.
Gneiss. Age: Precambrian to Paleozoic. About 0.8 mi of the line.
Age: Precambrian to Paleozoic. About 0.6 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 Peachtree Corners reaches the Gulf of America by way of the Chattahoochee and the Apalachicola: about 430 river miles.
Lakes on the way: Walter F George Reservoir, West Point Lake and Bartletts Ferry Lake.
