Wyanet’s center stands about 650 ft above sea level. Within three miles the land runs from 570 ft to 710 ft, a difference of 140 ft: gently rolling country. The highest named summit within 15 miles is Gravel Hill, about 830 ft, 7 miles southwest.
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 60×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Dolostone, limestone. Age: Silurian, 422 to 445 million years old. About 12 mi of the line.
Shale, limestone. Age: Late Pennsylvanian, 304 to 307 million years old. About 9 mi of the line.
Shale, sandstone, coal. Age: Middle Pennsylvanian to Late Pennsylvanian, 304 to 315 million years old. About 2 mi of the line.
Shale, sandstone. Age: Early Pennsylvanian to Middle Pennsylvanian, 307 to 324 million years old. About 1 mi of the line.

A raindrop that lands in Wyanet reaches the Gulf of America by way of Pond Creek, West Bureau Creek, Big Bureau Creek, the Illinois and the Mississippi: about 1,420 river miles.
Lake on the way: Peoria Lake.
1,190 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Wyanet; river miles along the main stem, rounded.
Wyanet has a hot-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 13° in January. A normal year brings about 36 inches of snow; with the rain, that comes to about 37 inches of water.
On November 14 Wyanet normally reaches 48° and falls to 30°. The record high is 74°, in 1999; the record low 0°, in 1996. The most rain on this date, 1.83 in, fell in 1926.
Normals 1991–2020 and records since 1893 at Walnut, 13 miles north. NOAA, through RCC-ACIS.
