Grover’s center stands about 5,080 ft above sea level. Within three miles the land runs from 5,030 ft to 5,240 ft, a difference of 210 ft: rolling country. The highest named summit within 15 miles is Panorama Point, about 5,420 ft, 14 miles northeast.
Under the town center the state geologic map shows White River Fm or Group (sandstone, claystone), from the Oligocene, 23 to 34 million years old.
The section below crosses 2 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 39×. 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, claystone. Age: Oligocene, 23 to 34 million years old. About 18 mi of the line.
Shale, claystone, sandstone. Age: Late Cretaceous, 66 to 100 million years old. About 7 mi of the line.

A raindrop that lands in Grover reaches the Gulf of America by way of the South Platte, the Platte, the Missouri and the Mississippi: about 2,390 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 Grover; river miles along the main stem, rounded.
Grover has a cold semi-arid climate. Summer afternoons average 87° in July; winter nights fall to about 14° in January. A normal year brings about 42 inches of snow; with the rain, that comes to about 17 inches of water.
On November 14 Grover normally reaches 50° and falls to 22°. The record high is 75°, in 1999; the record low −15°, in 2014. The most rain on this date, 0.21 in, fell in 2008.
