The Neosho Falls 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.
83° on Nov. 11, 1989, the hottest reading for this week of the year since 1904. Next is 81° in 1999.
Neosho Falls’s center stands about 980 ft above sea level. Within three miles the land runs from 960 ft to 1,030 ft, a difference of 70 ft: gently rolling country.
Under the town center the state geologic map shows Alluvium (sand, silt, clay), from the Pleistocene to Holocene, less than 2.6 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 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.
Shale, sandstone. Age: Carboniferous, 299 to 324 million years old. About 16 mi of the line.
Shale, limestone. Age: Carboniferous, 299 to 324 million years old. About 4 mi of the line.
Sand, silt, clay. Age: Pleistocene to Holocene, less than 2.6 million years old. About 3 mi of the line.
Gravel. Age: Tertiary, 2.6 to 66 million years old. About 0.4 mi of the line.

A raindrop that lands in Neosho Falls reaches the Gulf of America by way of the Neosho, the Arkansas and the Mississippi: about 1,300 river miles.
Lakes on the way: Murray Lake and Ozark Lake.
600 miles of the trip are on the Mississippi.

Neosho Falls 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 Neosho Falls 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.
