Arcadia’s center stands about 2,160 ft above sea level. Within three miles the land runs from 2,130 ft to 2,320 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 56×. 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.
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 Arcadia reaches the Gulf of America by way of the Middle Loup, the Loup, the Platte, the Missouri and the Mississippi: about 2,000 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 Arcadia; river miles along the main stem, rounded.
Arcadia has a hot-summer humid continental climate. Summer afternoons average 85° in July; winter nights fall to about 10° in January. A normal year brings about 31 inches of snow; with the rain, that comes to about 26 inches of water.
On November 14 Arcadia normally reaches 50° and falls to 23°. The record high is 74°, in 2025; the record low −9°, in 1940. The most rain on this date, 0.27 in, fell in 1972.
Normals 1991–2020 and records since 1893 at North Loup, 19 miles east-northeast, 190 ft lower. NOAA, through RCC-ACIS.
