Loomis’s center stands about 1,310 ft above sea level. Within three miles the land runs from 1,250 ft to 1,330 ft, a difference of 80 ft: gently 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 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. Age: Late Cretaceous, 66 to 100 million years old. About 11 mi of the line.
Chalk, marlstone, shale. Age: Late Cretaceous, 66 to 100 million years old. About 10 mi of the line.
Shale, bentonite. Age: Late Cretaceous, 66 to 100 million years old. About 3 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

A raindrop that lands in Loomis reaches the Gulf of America by way of Dry Run, the James, the Missouri and the Mississippi: about 2,110 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 Loomis; river miles along the main stem, rounded.
Loomis has a hot-summer humid continental climate. Summer afternoons average 87° in July; winter nights fall to about 9° in January. About 21 inches of rain fall in a normal year.
On November 14 Loomis normally reaches 46° and falls to 25°. The record high is 79°, in 2025; the record low −22°, in 1959. The most rain on this date, 0.46 in, fell in 1928.
Normals 1991–2020 and records since 1893 from the Mitchell Area threaded record (Mitchell Airport, 4 miles east-southeast). NOAA, through RCC-ACIS.
