Centreville’s center stands about 240 ft above sea level. Within three miles the land runs from 200 ft to 460 ft, a difference of 260 ft: rolling country. The highest named summit within 15 miles is Soap Hill, about 660 ft, 7 miles east.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 44×. 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, clay. Age: Cretaceous, 66 to 145 million years old. About 19 mi of the line.
Sand, clay. Age: Cretaceous, 66 to 145 million years old. About 4 mi of the line.
Sand. Age: Holocene, less than 12,000 years old. About 1 mi of the line.
Limestone, dolostone. Age: Cambrian to Ordovician, 445 to 542 million years old. About 0.4 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 Centreville reaches Mobile Bay and the Gulf of America by way of the Cahaba, the Alabama and the Mobile: about 330 river miles.
200 miles of the trip are on the Alabama.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Centreville; river miles along the main stem, rounded.
