Bronson’s center stands about 1,070 ft above sea level. Within three miles the land runs from 990 ft to 1,110 ft, a difference of 120 ft: gently rolling country.
Under the town center the state geologic map shows Kansas City Group (limestone, shale), from the Carboniferous, 299 to 324 million years old.
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.
Limestone, shale. Age: Carboniferous, 299 to 324 million years old. About 18 mi of the line.
Shale, limestone, sandstone. Age: Carboniferous, 299 to 324 million years old. About 6 mi of the line.
Shale, sandstone. Age: Carboniferous, 299 to 324 million years old. About 0.9 mi of the line.

A raindrop that lands in Bronson reaches the Gulf of America by way of the Marmaton, the Little Osage, the Osage, the Missouri and the Mississippi: about 1,670 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 Bronson; river miles along the main stem, rounded.
Bronson has a hot-summer humid continental climate. Summer afternoons average 88° in July; winter nights fall to about 20° in January. A normal year brings about 7 inches of snow; with the rain, that comes to about 42 inches of water.
On November 14 Bronson normally reaches 57° and falls to 35°. The record high is 77°, in 1964; the record low 10°, in 1959. The most rain on this date, 1.04 in, fell in 1909.
