5.47 inches of rain fell in two days, the most for this week of the year since records began in 1892. The next wettest, 4.29 inches, fell in 1958.
Chetopa’s center stands about 830 ft above sea level. Within three miles the land runs from 780 ft to 890 ft, a difference of 110 ft: gently rolling country. The highest named summit within 15 miles is Blue Mound, about 990 ft, 15 miles east.
Under the town center the state geologic map shows Cherokee Group (sandstone, shale), from the Carboniferous, 299 to 324 million years old.
The section below crosses 6 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.
Sandstone, shale. Age: Carboniferous, 299 to 324 million years old. About 9 mi of the line.
Sand, silt, clay. Age: Pleistocene to Holocene, less than 2.6 million years old. About 7 mi of the line.
Shale. Age: Carboniferous, 299 to 324 million years old. About 3 mi of the line.
Shale, limestone, sandstone. Age: Carboniferous, 299 to 324 million years old. About 3 mi of the line.
Limestone, shale. Age: Carboniferous, 299 to 324 million years old. About 2 mi of the line.
Limestone, shale. Age: Carboniferous, 299 to 324 million years old. About 0.7 mi of the line.

A raindrop that lands in Chetopa reaches the Gulf of America by way of Town Creek, the Neosho, the Arkansas and the Mississippi: about 1,170 river miles.
Lakes on the way: Murray Lake and Ozark Lake.
600 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Chetopa; river miles along the main stem, rounded.
Chetopa has a humid subtropical climate. Summer afternoons average 90° in July; winter nights fall to about 23° in January. A normal year brings about 7 inches of snow; with the rain, that comes to about 46 inches of water.
On November 14 Chetopa normally reaches 58° and falls to 37°. The record high is 82°, in 1964; the record low 10°, in 1986. The most rain on this date, 3.25 in, fell in 1985.
Normals 1991–2020 and records since 1892 at Columbus, 17 miles east-northeast. NOAA, through RCC-ACIS.
