Adrian’s center stands about 300 ft above sea level. Within three miles the land runs from 210 ft to 390 ft, a difference of 180 ft: gently rolling country.
Under the town center the state geologic map shows Neogene undifferentiated (sandstone, claystone), from the Tertiary Neogene, 2.6 to 23 million years old.
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.
Sandstone, claystone. Age: Tertiary Neogene, 2.6 to 23 million years old. About 24 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 Adrian reaches the Atlantic Ocean by way of the Ohoopee and the Altamaha: about 170 river miles.
90 miles of the trip are on the Altamaha.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Adrian; river miles along the main stem, rounded.
