La Paz’s center stands about 860 ft above sea level. Within three miles the land runs from 800 ft to 900 ft, a difference of 100 ft: gently rolling country.
Under the town center the state geologic map shows Ellsworth Shale, from the Devonian to Carboniferous, 324 to 422 million years old.
The section below crosses 2 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: Devonian to Carboniferous, 324 to 422 million years old. About 23 mi of the line.
Black-shale. Age: Devonian, 359 to 422 million years old. About 1 mi of the line.

A raindrop that lands in La Paz reaches the Gulf of America by way of the Yellow, the Kankakee, the Illinois and the Mississippi: about 1,630 river miles.
Lake on the way: Peoria Lake.
1,190 miles of the trip are on the Mississippi.

La Paz has a warm-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 15° in January. A normal year brings about 37 inches of snow; with the rain, that comes to about 42 inches of water.
On November 14 La Paz normally reaches 48° and falls to 30°. The record high is 72°, in 1989; the record low 8°, in 2019. The most rain on this date, 0.40 in, fell in 2024.
