Sweet Water’s center stands about 200 ft above sea level. Within three miles the land runs from 140 ft to 330 ft, a difference of 190 ft: gently rolling country.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 56×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Silt, clay. Age: Paleocene, 56 to 66 million years old. About 15 mi of the line.
Sand. Age: Holocene, less than 12,000 years old. About 6 mi of the line.
Clay, sand. Age: Paleocene, 56 to 66 million years old. About 1 mi of the line.
Sand. Age: Pleistocene, less than 2.6 million years old. About 1 mi of the line.
Sand, clay. Age: Paleocene, 56 to 66 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 Sweet Water reaches Mobile Bay and the Gulf of America by way of Shell Creek, Sweetwater Creek, Horse Creek, the Tombigbee and the Mobile: about 190 river miles.
120 miles of the trip are on the Tombigbee.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Sweet Water; river miles along the main stem, rounded.
