Ashton’s center stands about 2,040 ft above sea level. Within three miles the land runs from 2,010 ft to 2,200 ft, a difference of 190 ft: gently rolling country.
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 52×. 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 Ashton reaches the Gulf of America by way of Oak Creek, the Middle Loup, the Loup, the Platte, the Missouri and the Mississippi: about 1,980 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 Ashton; river miles along the main stem, rounded.
Ashton 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 24 inches of snow; with the rain, that comes to about 26 inches of water.
On November 14 Ashton normally reaches 52° and falls to 24°. The record high is 75°, in 1975; the record low −8°, in 1940. The most rain on this date, 0.62 in, fell in 1972.
