80° on Nov. 16, 2016, the hottest reading for this week of the year since 1872. Next is 79° in 1990.
Comanche Creek’s center stands about 5,670 ft above sea level. Within three miles the land runs from 5,560 ft to 5,760 ft, a difference of 200 ft: gently rolling country.
Under the town center the state geologic map shows Eolian deposits (sand, silt), from the Quaternary, less than 2.6 million years old.
The section below crosses 5 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.
Sand, silt. Age: Quaternary, less than 2.6 million years old. About 10 mi of the line.
Arkose, shale, mudstone. Age: Late Cretaceous to Paleocene, 56 to 100 million years old. About 7 mi of the line.
Sandstone, claystone. Age: Oligocene, 23 to 34 million years old. About 3 mi of the line.
Arkose, conglomerate, shale. Age: Paleocene to Eocene, 34 to 66 million years old. About 2 mi of the line.
Unconsolidated. Age: Quaternary, less than 2.6 million years old. About 2 mi of the line.

A raindrop that lands in Comanche Creek reaches the Gulf of America by way of Little Comanche Creek, Comanche Creek, Kiowa Creek, the South Platte, the Platte, the Missouri and the Mississippi: about 2,390 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 Comanche Creek; river miles along the main stem, rounded.
Comanche Creek has a cold semi-arid climate. Summer afternoons average 90° in July; winter nights fall to about 19° in January. About 14 inches of rain fall in a normal year.
On November 14 Comanche Creek normally reaches 54° and falls to 27°. The record high is 79°, in 1990; the record low −7°, in 1872. The most rain on this date, 0.60 in, fell in 1994.
