Eldon’s center stands about 930 ft above sea level. Within three miles the land runs from 740 ft to 1,000 ft, a difference of 260 ft: rolling country.
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 43×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.

A raindrop that lands in Eldon reaches the Gulf of America by way of Blythes Creek, South Moreau Creek, the Moreau, the Missouri and the Mississippi: about 1,370 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Eldon; river miles along the main stem, rounded.
Eldon has a hot-summer humid continental climate. Summer afternoons average 89° in July; winter nights fall to about 22° in January. About 45 inches of rain fall in a normal year.
