Cromwell’s center stands about 1,280 ft above sea level. Within three miles the land runs from 1,190 ft to 1,310 ft, a difference of 120 ft: gently rolling country.
Under the town center the state geologic map shows Shawnee Group (limestone, shale), from the Late Pennsylvanian, 299 to 307 million years old.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. 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, mudstone. Age: Late Pennsylvanian, 299 to 307 million years old. About 11 mi of the line.
Limestone, shale. Age: Late Pennsylvanian, 299 to 307 million years old. About 9 mi of the line.
Limestone, shale. Age: Late Pennsylvanian, 299 to 307 million years old. About 4 mi of the line.

A raindrop that lands in Cromwell reaches the Gulf of America by way of the West Platte, the Platte, the Missouri and the Mississippi: about 1,740 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 Cromwell; river miles along the main stem, rounded.
Cromwell has a hot-summer humid continental climate. Summer afternoons average 85° in July; winter nights fall to about 11° in January. About 38 inches of rain fall in a normal year.
On November 14 Cromwell normally reaches 49° and falls to 27°. The record high is 72°, in 1964; the record low −1°, in 1916. The most rain on this date, 0.84 in, fell in 1972.
