The Bentonville plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
4.17 inches of rain fell in two days, the most for this week of the year since records began in 1898. The next wettest, 3.54 inches, fell in 2015.
Bentonville’s center stands about 1,300 ft above sea level. Within three miles the land runs from 1,070 ft to 1,330 ft, a difference of 260 ft: rolling country. The highest named summit within 15 miles is Humphery Mountain, about 1,720 ft, 14 miles east.
Under the town center the state geologic map shows Boone Formation (limestone), from the Carboniferous, 324 to 359 million years old.
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 47×. 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. Age: Carboniferous, 324 to 359 million years old. About 21 mi of the line.
Dolostone. Age: Early Ordovician, 471 to 487 million years old. About 2 mi of the line.
Limestone, sandstone. Age: Early Devonian to Late Devonian, 359 to 422 million years old. About 1 mi of the line.
Shale, limestone, dolostone. Age: Early Devonian to Carboniferous, 324 to 422 million years old. About 0.5 mi of the line.

A raindrop that lands in Bentonville reaches the Gulf of America by way of Little Osage Creek, Osage Creek, the Illinois, the Arkansas and the Mississippi: about 1,110 river miles.
Lakes on the way: Murray Lake, Tenkiller Ferry Lake and Ozark Lake.
600 miles of the trip are on the Mississippi.

Bentonville has a humid subtropical climate. Summer afternoons average 93° in July; winter nights fall to about 29° in January. A normal year brings about 12 inches of snow; with the rain, that comes to about 49 inches of water.
On November 14 Bentonville normally reaches 61° and falls to 40°. The record high is 78°, in 1999; the record low 7°, in 1940. The most rain on this date, 4.04 in, fell in 1993.
