The Waresboro 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.
Waresboro’s center stands about 150 ft above sea level. Within three miles the land runs from 130 ft to 200 ft, a difference of 70 ft: gently rolling country.
Under the town center the state geologic map shows Pleistocene-Pliocene sands and gravels (sand, gravel), from the Pliocene to Pleistocene, less than 5.3 million years old.
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.
Sand, gravel. Age: Pliocene to Pleistocene, less than 5.3 million years old. About 22 mi of the line.
Fine-detrital. Age: Quaternary, less than 2.6 million years old. About 2 mi of the line.
Sandstone, claystone. Age: Tertiary Neogene, 2.6 to 23 million years old. About 0.8 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.
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 Waresboro reaches the Atlantic Ocean by way of Cox Creek and the Satilla: about 170 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Waresboro; river miles along the main stem, rounded.
