Bridgeport’s center stands about 670 ft above sea level. Within three miles the land runs from 600 ft to 1,520 ft, a difference of 920 ft: steep hill country. The highest named summit within 15 miles is Red Hill, about 1,990 ft, 14 miles north-northwest.
Under the town center the state geologic map shows Knox Group undifferentiated (dolostone, limestone), from the Cambrian to Ordovician, 445 to 542 million years old.
The section below crosses 14 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 16×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.

A raindrop that lands in Bridgeport reaches the Gulf of America by way of the Tennessee, the Ohio and the Mississippi: about 1,430 river miles.
Lakes on the way: Guntersville Lake, White Lake (historical) and Pickwick Lake.
970 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Bridgeport; river miles along the main stem, rounded.
