Doe Run’s center stands about 970 ft above sea level. Within three miles the land runs from 850 ft to 1,340 ft, a difference of 490 ft: hilly country. The highest named summit within 15 miles is Buford Mountain, about 1,760 ft, 11 miles west-southwest.
Under the town center the state geologic map shows Elvins Group - (including Derby-Doerun Dolomite, Davis Formation), Bonneterre Dolomite (dolostone, shale, siltstone), from the Cambrian, 487 to 497 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 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.
Dolostone, shale, siltstone. Age: Cambrian, 487 to 497 million years old. About 10 mi of the line.
Rhyolite. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 4 mi of the line.
Alkali-feldspar-granite. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 4 mi of the line.
Sandstone. Age: Cambrian, 487 to 497 million years old. About 4 mi of the line.
Dolostone. Age: Cambrian, 487 to 497 million years old. About 1 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 Doe Run reaches the Gulf of America by way of Doe Run Creek, the Saint Francis and the Mississippi: about 1,090 river miles.
690 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Doe Run; river miles along the main stem, rounded.
