85° on Nov. 15, 2025, the hottest reading for this week of the year since 1893. Next is 82° in 2005.
Ericson’s center stands about 2,040 ft above sea level. Within three miles the land runs from 2,000 ft to 2,190 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 62×. 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 Ericson reaches the Gulf of America by way of the Cedar River, the Loup, the Platte, the Missouri and the Mississippi: about 1,990 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 Ericson; river miles along the main stem, rounded.
Ericson has a hot-summer humid continental climate. Summer afternoons average 86° in July; winter nights fall to about 11° in January. About 27 inches of rain fall in a normal year.
On November 14 Ericson normally reaches 49° and falls to 23°. The record high is 79°, in 1999; the record low −8°, in 1986. The most rain on this date, 0.38 in, fell in 2021.
Normals 1991–2020 and records since 1893 at Ericson 8 WNW, 8 miles west-northwest. NOAA, through RCC-ACIS.
