Gruver’s center stands about 1,300 ft above sea level. Within three miles the land runs from 1,260 ft to 1,320 ft, a difference of 60 ft: gently rolling country.
Under the town center the state geologic map shows Dakata and Windrow Formations (sandstone, shale), from the Early Cretaceous to Late Cretaceous, 94 to 113 million years old.
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.
Sandstone, shale. Age: Early Cretaceous to Late Cretaceous, 94 to 113 million years old. About 24 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

A raindrop that lands in Gruver reaches the Gulf of America by way of Jack Creek, the Des Moines and the Mississippi: about 1,740 river miles.
Lakes on the way: Roberts Creek and Big Creek Pounding Area.
1,330 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Gruver; river miles along the main stem, rounded.
Gruver has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 7° in January. About 29 inches of rain fall in a normal year.
On November 14 Gruver normally reaches 43° and falls to 24°. The record high is 74°, in 2025; the record low 1°, in 2014. The most rain on this date, 0.06 in, fell in 2008.
