Gandy’s center stands about 2,900 ft above sea level. Within three miles the land runs from 2,830 ft to 3,070 ft, a difference of 240 ft: rolling country. The highest named summit within 15 miles is Judkins Table, about 3,120 ft, 14 miles east.
Under the town center the state geologic map shows Ogallala Group or Formation (siltstone-mudstone, conglomerate-sandstone), from the Miocene, 5.3 to 23 million years old.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 49×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Siltstone-mudstone, conglomerate-sandstone. Age: Miocene, 5.3 to 23 million years old. About 24 mi of the line.

A raindrop that lands in Gandy reaches the Gulf of America by way of the South Loup, the Middle Loup, the Loup, the Platte, the Missouri and the Mississippi: about 2,130 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 Gandy; river miles along the main stem, rounded.
Gandy has a hot-summer humid continental climate. Summer afternoons average 87° in July; winter nights fall to about 12° in January. A normal year brings about 37 inches of snow; with the rain, that comes to about 24 inches of water.
On November 14 Gandy normally reaches 51° and falls to 23°. The record high is 80°, in 1999; the record low −2°, in 2014. The most rain on this date, 0.04 in, fell in 1993.
Normals 1991–2020 and records since 1989 at Stapleton 5 W, 7 miles west, 120 ft higher. NOAA, through RCC-ACIS.
