Cedar Bluff’s center stands about 600 ft above sea level. Within three miles the land runs from 560 ft to 900 ft, a difference of 340 ft: rolling country. The highest named summit within 15 miles is Weisner Mountain, about 1,850 ft, 14 miles south-southwest.
Under the town center the state geologic map shows Conasauga Formation (dolostone, limestone), from the Cambrian, 487 to 542 million years old.
The section below crosses 9 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 23×. 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: Cambrian, 487 to 542 million years old. About 5 mi of the line.
Sandstone, conglomerate. Age: Carboniferous, 299 to 324 million years old. About 4 mi of the line.
Sand. Age: Pleistocene, less than 2.6 million years old. About 3 mi of the line.
Dolostone, limestone. Age: Cambrian to Ordovician, 445 to 542 million years old. About 2 mi of the line.
Sandstone, shale. Age: Silurian, 422 to 445 million years old. About 1 mi of the line.
Limestone. Age: Carboniferous, 324 to 359 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. 3 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 Cedar Bluff reaches Mobile Bay and the Gulf of America by way of the Coosa, the Alabama and the Mobile: about 600 river miles.
Lake on the way: Lay Lake.
310 miles of the trip are on the Alabama.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Cedar Bluff; river miles along the main stem, rounded.
