The Rayville 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.
Rayville’s center stands about 990 ft above sea level. Within three miles the land runs from 750 ft to 1,030 ft, a difference of 280 ft: rolling country.
Under the town center the state geologic map shows Kansas City Group (limestone, shale), from the Carboniferous, 299 to 324 million years old.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 48×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Limestone, shale. Age: Carboniferous, 299 to 324 million years old. About 14 mi of the line.
Limestone, shale. Age: Carboniferous, 299 to 324 million years old. About 4 mi of the line.
Clay, silt, sand. Age: Holocene, less than 12,000 years old. About 3 mi of the line.
Shale, sandstone. Age: Carboniferous, 299 to 324 million years old. About 3 mi of the line.
Shale, limestone. Age: Carboniferous, 299 to 324 million years old. About 0.1 mi of the line.

A raindrop that lands in Rayville reaches the Gulf of America by way of the West Fork Crooked, the Crooked River, the Missouri and the Mississippi: about 1,500 river miles.
1,170 miles of the trip are on the Mississippi.
