3.64 inches of rain fell in two days, the most for this week of the year since records began in 1946. The next wettest, 3.33 inches, fell in 1957.
Fanshawe’s center stands about 550 ft above sea level. Within three miles the land runs from 500 ft to 980 ft, a difference of 480 ft: hilly country. The highest named summit within 15 miles is Blue Mountain, about 1,970 ft, 12 miles southeast.
Under the town center the state geologic map shows McAlester Formation (shale, sandstone), from the Carboniferous, 299 to 324 million years old.
The section below crosses 9 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 13×. 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, sandstone. Age: Carboniferous, 299 to 324 million years old. About 8 mi of the line.
Shale, sandstone. Age: Carboniferous, 299 to 324 million years old. About 6 mi of the line.
Sandstone. Age: Carboniferous, 299 to 324 million years old. About 2 mi of the line.
Fine-detrital. Age: Holocene, less than 12,000 years old. About 2 mi of the line.
Coarse-detrital, fine-detrital. Age: Pleistocene, less than 2.6 million years old. About 2 mi of the line.
Shale, sandstone. Age: Carboniferous, 299 to 324 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. 3 smaller units along the line are not listed.

A raindrop that lands in Fanshawe reaches the Gulf of America by way of Coal Creek, the Fourche Maline, the Poteau, the Arkansas and the Mississippi: about 1,000 river miles.
Lakes on the way: Murray Lake, Ozark Lake and Wister Lake.
600 miles of the trip are on the Mississippi.

Fanshawe has a cold desert climate. Summer afternoons average 93° in July; winter nights fall to about 27° in January. Barely 0.0 inches of rain fall in a normal year.
On November 14 Fanshawe normally reaches 64° and falls to 40°. The record high is 86°, in 1955; the record low 16°, in 1963. The most rain on this date, 0.63 in, fell in 1970.
Normals 1991–2020 and records since 1946 at Wister 3 S, 12 miles east. NOAA, through RCC-ACIS.
