Spring Creek Colony’s center stands about 1,660 ft above sea level. Within three miles the land runs from 1,570 ft to 2,010 ft, a difference of 440 ft: hilly country.
Under the town center the state geologic map shows Pierre Shale (shale, bentonite), from the Late Cretaceous, 66 to 100 million years old.
The section below crosses 2 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 27×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale, bentonite. Age: Late Cretaceous, 66 to 100 million years old. About 15 mi of the line.
Shale. Age: Late Cretaceous, 66 to 100 million years old. About 9 mi of the line.

A raindrop that lands in Spring Creek Colony reaches the Gulf of America by way of the Elm, the James, the Missouri and the Mississippi: about 2,460 river miles.
1,170 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Spring Creek Colony; river miles along the main stem, rounded.
