3.95 inches of rain fell in two days, the most for this week of the year since records began in 1887. The next wettest, 3.65 inches, fell in 2009.
Eldred’s center stands about 450 ft above sea level. Within three miles the land runs from 420 ft to 680 ft, a difference of 260 ft: rolling country. The highest named summit within 15 miles is Franklin Hill, about 820 ft, 15 miles south-southwest.
Under the town center the state geologic map shows Glen Park Formation, Hannibal Shale, Chouteau Limestone, McCraney Limestone, Prospect Hill Siltstone, and Starrs Cave Limestone (limestone, shale), from the Early Mississippian, 347 to 359 million years old.
The section below crosses 7 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 53×. 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. Age: Early Mississippian to Middle Mississippian, 331 to 359 million years old. About 13 mi of the line.
Limestone. Age: Middle Mississippian, 331 to 347 million years old. About 4 mi of the line.
Limestone, shale. Age: Early Mississippian, 347 to 359 million years old. About 3 mi of the line.
Dolostone, limestone. Age: Silurian, 422 to 445 million years old. About 2 mi of the line.
Shale. Age: Middle Devonian to Late Devonian, 359 to 388 million years old. About 1 mi of the line.
Shale, sandstone. Age: Early Pennsylvanian to Middle Pennsylvanian, 307 to 324 million years old. About 0.4 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 1 smaller unit along the line are not listed.

A raindrop that lands in Eldred reaches the Gulf of America by way of Hurricane Creek, the Illinois and the Mississippi: about 1,230 river miles.

Eldred has a hot-summer humid continental climate. Summer afternoons average 86° in July; winter nights fall to about 18° in January. A normal year brings about 18 inches of snow; with the rain, that comes to about 40 inches of water.
On November 14 Eldred normally reaches 53° and falls to 33°. The record high is 80°, in 1931; the record low 7°, in 1986. The most rain on this date, 1.40 in, fell in 1913.
