The La Grange 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.
3.14 inches of rain fell in two days, the most for this week of the year since records began in 1945. The next wettest, 3.08 inches, fell in 2024.
La Grange’s center stands about 860 ft above sea level. Within three miles the land runs from 700 ft to 910 ft, a difference of 210 ft: rolling country.
Under the town center the state geologic map shows Laurel Dolomite, Osgood Formation, and Brassfield Dolomite, undivided (dolostone), from the Silurian, 422 to 445 million years old.
The section below crosses 8 rock units mapped at the surface.

Dolostone. Age: Ordovician, 445 to 487 million years old. About 8 mi of the line.
Limestone. Age: Ordovician, 445 to 487 million years old. About 5 mi of the line.
Dolostone. Age: Silurian, 422 to 445 million years old. About 3 mi of the line.
Limestone. Age: Silurian, 422 to 445 million years old. About 3 mi of the line.
Limestone. Age: Ordovician, 445 to 487 million years old. About 2 mi of the line.
Limestone, dolostone. Age: Devonian, 359 to 422 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. 2 smaller units along the line are not listed.

A raindrop that lands in La Grange reaches the Gulf of America by way of the North Fork Currys Fork, the Currys Fork, the Floyds Fork, the Salt River, the Ohio and the Mississippi: about 1,400 river miles.
970 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of La Grange; river miles along the main stem, rounded.
La Grange has a humid subtropical climate. Summer afternoons average 89° in July; winter nights fall to about 28° in January. A normal year brings about 13 inches of snow; with the rain, that comes to about 48 inches of water.
On November 14 La Grange normally reaches 58° and falls to 40°. The record high is 76°, in 2011; the record low 15°, in 1986. The most rain on this date, 0.89 in, fell in 2024.
