The Varnado 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.
6.76 inches of rain fell in two days, the most for this week of the year since records began in 1896. The next wettest, 3.95 inches, fell in 1947.
Varnado’s center stands about 130 ft above sea level. Within three miles the land runs from 100 ft to 220 ft, a difference of 120 ft: gently rolling country.
Under the town center the state geologic map shows Prairie Terraces (clay, silt, sand), from the Pleistocene, less than 2.6 million years old.
The section below crosses 6 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.
Clay, silt, sand. Age: Pleistocene, less than 2.6 million years old. About 6 mi of the line.
Sand, gravel. Age: Pliocene to Pleistocene, less than 5.3 million years old. About 5 mi of the line.
Clay. Age: Holocene, less than 12,000 years old. About 5 mi of the line.
Fine-detrital, coarse-detrital. Age: Holocene, less than 12,000 years old. About 4 mi of the line.
Clay, silt, sand. Age: Pleistocene, less than 2.6 million years old. About 3 mi of the line.
Clay, sand. Age: Miocene, 5.3 to 23 million years old. About 2 mi of the line.

A raindrop that lands in Varnado reaches the Gulf of America by way of Pushepatapa Creek and the Pearl: about 90 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Varnado; river miles along the main stem, rounded.
Varnado has a humid subtropical climate. Summer afternoons average 91° in July; winter nights fall to about 38° in January. About 65 inches of rain fall in a normal year.
On November 14 Varnado normally reaches 69° and falls to 46°. The record high is 84°, in 1924; the record low 25°, in 2019. The most rain on this date, 4.91 in, fell in 1961.
