The Spearville 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.
87° on Nov. 16, 2016, the hottest reading for this week of the year since 1874. Next is 83° in 1894.
Spearville’s center stands about 2,460 ft above sea level. Within three miles the land runs from 2,400 ft to 2,460 ft, a difference of 60 ft: gently rolling country.
Under the town center the state geologic map shows Loess (silt), from the Pleistocene to Holocene, less than 2.6 million years old.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 62×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Silt. Age: Pleistocene to Holocene, less than 2.6 million years old. About 24 mi of the line.

A raindrop that lands in Spearville reaches the Gulf of America by way of Cow Creek, Coon Creek, the Arkansas and the Mississippi: about 1,540 river miles.
Lakes on the way: Murray Lake and Ozark Lake.
600 miles of the trip are on the Mississippi.

Spearville has a humid subtropical climate. Summer afternoons average 94° in July; winter nights fall to about 20° in January. A normal year brings about 19 inches of snow; with the rain, that comes to about 22 inches of water.
On November 14 Spearville normally reaches 58° and falls to 31°. The record high is 83°, in 2025; the record low 2°, in 1940. The most rain on this date, 0.71 in, fell in 1947.
