Stewartsville’s center stands about 1,000 ft above sea level. Within three miles the land runs from 930 ft to 1,050 ft, a difference of 120 ft: gently rolling country.
Under the town center the state geologic map shows Lansing Group (shale, limestone), from the Carboniferous, 299 to 324 million years old.
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, limestone. Age: Carboniferous, 299 to 324 million years old. About 24 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 Stewartsville reaches the Gulf of America by way of Castile Creek, the Platte, the Missouri and the Mississippi: about 1,630 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 Stewartsville; river miles along the main stem, rounded.
