5.61 inches of rain fell in two days, the most for this week of the year since records began in 1944. The next wettest, 4.27 inches, fell in 1985.
Osawatomie’s center stands about 870 ft above sea level. Within three miles the land runs from 840 ft to 960 ft, a difference of 120 ft: gently rolling country.
The section below crosses 4 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 16 mi of the line.
Shale, sandstone. Age: Carboniferous, 299 to 324 million years old. About 3 mi of the line.
Shale, limestone. Age: Carboniferous, 299 to 324 million years old. About 3 mi of the line.
Sand, silt, clay. Age: Pleistocene to Holocene, less than 2.6 million years old. About 2 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 Osawatomie reaches the Gulf of America by way of the Marais des Cygnes, the Osage, the Missouri and the Mississippi: about 1,680 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 Osawatomie; river miles along the main stem, rounded.
Osawatomie has a hot-summer humid continental climate. Summer afternoons average 89° in July; winter nights fall to about 19° in January. A normal year brings about 8 inches of snow; with the rain, that comes to about 39 inches of water.
