The Waverly 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.
81° on Nov. 14, 1999, the hottest reading for this week of the year since 1893. Next is 79° in 1949.
Waverly’s center stands about 810 ft above sea level. Within three miles the land runs from 650 ft to 840 ft, a difference of 190 ft: gently rolling country.
Under the town center the state geologic map shows Holocene series (clay, silt, sand), from the Holocene, less than 12,000 years old.
The section below crosses 3 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.
Clay, silt, sand. Age: Holocene, less than 12,000 years old. About 12 mi of the line.
Limestone, shale. Age: Carboniferous, 299 to 324 million years old. About 12 mi of the line.
Sandstone. Age: Carboniferous, 299 to 324 million years old. About 0.4 mi of the line.

A raindrop that lands in Waverly reaches the Gulf of America by way of the Salt Fork, the Blackwater, the Lamine, the Missouri and the Mississippi: about 1,430 river miles.
1,170 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Waverly; river miles along the main stem, rounded.
Waverly has a hot-summer humid continental climate. Summer afternoons average 88° in July; winter nights fall to about 17° in January. A normal year brings about 13 inches of snow; with the rain, that comes to about 40 inches of water.
On November 14 Waverly normally reaches 54° and falls to 32°. The record high is 81°, in 1999; the record low 11°, in 2018. The most rain on this date, 0.48 in, fell in 1993.
