The Warren AFB 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.
75° on Nov. 15, 1999, the hottest reading for this week of the year since 1871. Next is 75° in 2016.
Warren AFB’s center stands about 6,110 ft above sea level. Within three miles the land runs from 6,050 ft to 6,300 ft, a difference of 250 ft: rolling country. The highest named summit within 15 miles is Terry Anticline, about 6,450 ft, 9 miles south.
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 20×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sandstone, claystone, conglomerate. Age: Late Miocene, 5.3 to 12 million years old. About 23 mi of the line.
Clay, silt, sand. Age: Pleistocene to Holocene, less than 2.6 million years old. About 0.8 mi of the line.

A raindrop that lands in Warren AFB reaches the Gulf of America by way of the South Platte, the Platte, the Missouri and the Mississippi: about 2,450 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 Warren AFB; river miles along the main stem, rounded.
Warren AFB has a cold semi-arid climate. Summer afternoons average 84° in July; winter nights fall to about 18° in January. A normal year brings about 63 inches of snow; with the rain, that comes to about 15 inches of water.
On November 14 Warren AFB normally reaches 48° and falls to 25°. The record high is 71°, in 2025; the record low −7°, in 1872. The most rain on this date, 0.25 in, fell in 2009.
