The Chouteau plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
Chouteau’s center stands about 620 ft above sea level. Within three miles the land runs from 570 ft to 700 ft, a difference of 130 ft: gently rolling country. The highest named summit within 15 miles is Hadley Mountain, about 960 ft, 10 miles southeast.
Under the town center the state geologic map shows Atoka Formation (shale, sandstone), from the Carboniferous, 299 to 324 million years old.
The section below crosses 8 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 50×. 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. Age: Carboniferous, 299 to 324 million years old. About 7 mi of the line.
Shale, sandstone. Age: Carboniferous, 299 to 324 million years old. About 6 mi of the line.
Shale, sandstone. Age: Carboniferous, 299 to 324 million years old. About 3 mi of the line.
Fine-detrital. Age: Holocene, less than 12,000 years old. About 3 mi of the line.
Coarse-detrital, fine-detrital. Age: Pleistocene, less than 2.6 million years old. About 3 mi of the line.
Chert, limestone. Age: Carboniferous, 324 to 359 million years old. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 2 smaller units along the line are not listed.

A raindrop that lands in Chouteau reaches the Gulf of America by way of Chouteau Creek, the Neosho, the Arkansas and the Mississippi: about 1,050 river miles.
Lakes on the way: Murray Lake and Ozark Lake.
600 miles of the trip are on the Mississippi.
