The Washburn plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
85° on Nov. 16, 2021, the hottest reading for this week of the year since 1892. Next is 85° in 2025.
Washburn’s center stands about 3,530 ft above sea level. Within three miles the land runs from 3,440 ft to 3,540 ft, a difference of 100 ft: gently rolling country.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sand. Age: Pleistocene, less than 2.6 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.

Washburn has a cold semi-arid climate. Summer afternoons average 93° in July; winter nights fall to about 25° in January. A normal year brings about 17 inches of snow; with the rain, that comes to about 20 inches of water.
On November 14 Washburn normally reaches 62° and falls to 34°. The record high is 85°, in 2025; the record low 5°, in 1916. The most rain on this date, 1.09 in, fell in 1924.
