Hayesville’s center stands about 790 ft above sea level. Within three miles the land runs from 660 ft to 810 ft, a difference of 150 ft: gently rolling country.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Dolostone, limestone. Age: Early Mississippian to Middle Mississippian, 331 to 359 million years old. About 10 mi of the line.
Shale, sandstone, siltstone. Age: Early Pennsylvanian to Middle Pennsylvanian, 307 to 324 million years old. About 8 mi of the line.
Dolostone, limestone. Age: Middle Mississippian to Late Mississippian, 324 to 347 million years old. About 7 mi of the line.

A raindrop that lands in Hayesville reaches the Gulf of America by way of Troublesome Creek, the North Skunk, the Skunk and the Mississippi: about 1,490 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Hayesville; river miles along the main stem, rounded.
