The Wilsey 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.
85° on Nov. 17, 2016, the hottest reading for this week of the year since 1964. Next is 83° in 1999.
Wilsey’s center stands about 1,510 ft above sea level. Within three miles the land runs from 1,420 ft to 1,540 ft, a difference of 120 ft: gently rolling country.
Under the town center the state geologic map shows Chase Group (shale, limestone), from the Permian, 252 to 299 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 57×. 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, limestone. Age: Permian, 252 to 299 million years old. About 19 mi of the line.
Shale. Age: Permian, 252 to 299 million years old. About 4 mi of the line.
Sand, silt, clay. Age: Pleistocene to Holocene, less than 2.6 million years old. About 1 mi of the line.
Limestone, shale. Age: Permian, 252 to 299 million years old. About 0.3 mi of the line.

A raindrop that lands in Wilsey reaches the Gulf of America by way of Elm Creek, the Neosho, the Arkansas and the Mississippi: about 1,450 river miles.
Lakes on the way: Murray Lake and Ozark Lake.
600 miles of the trip are on the Mississippi.

Wilsey has a hot-summer humid continental climate. Summer afternoons average 90° in July; winter nights fall to about 20° in January. A normal year brings about 12 inches of snow; with the rain, that comes to about 35 inches of water.
On November 14 Wilsey normally reaches 56° and falls to 34°. The record high is 83°, in 1999; the record low 8°, in 1986. The most rain on this date, 0.26 in, fell in 1993.
