The Whitharral 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.
86° on Nov. 16, 2025, the hottest reading for this week of the year since 1966. Next is 85° in 1967.
Whitharral’s center stands about 3,480 ft above sea level. Within three miles the land runs from 3,440 ft to 3,520 ft, a difference of 80 ft: gently rolling country.
The section below crosses 2 rock units mapped at the surface.
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 19 mi of the line.
Sand. Age: Late Miocene to Pliocene, 2.6 to 12 million years old. About 6 mi of the line.

Whitharral has a cold semi-arid climate. Summer afternoons average 92° in July; winter nights fall to about 23° in January. A normal year brings about 7 inches of snow; with the rain, that comes to about 18 inches of water.
On November 14 Whitharral normally reaches 64° and falls to 32°. The record high is 85°, in 2025; the record low 6°, in 1976. The most rain on this date, 0.38 in, fell in 2004.
