84° on Nov. 13, 1999, the hottest reading for this week of the year since 1893. Next is 83° in 2016.
Collyer’s center stands about 2,580 ft above sea level. Within three miles the land runs from 2,490 ft to 2,620 ft, a difference of 130 ft: gently rolling country.
Under the town center the state geologic map shows Loess (silt), from the Pleistocene to Holocene, less than 2.6 million years old.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 48×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Silt. Age: Pleistocene to Holocene, less than 2.6 million years old. About 17 mi of the line.
Arkose. Age: Miocene, 5.3 to 23 million years old. About 7 mi of the line.
Shale, limestone. Age: Late Cretaceous, 66 to 100 million years old. About 0.6 mi of the line.

A raindrop that lands in Collyer reaches the Gulf of America by way of Big Creek, the Smoky Hill, the Kansas, the Missouri and the Mississippi: about 2,110 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 Collyer; river miles along the main stem, rounded.
Collyer has a hot-summer humid continental climate. Summer afternoons average 90° in July; winter nights fall to about 17° in January. A normal year brings about 20 inches of snow; with the rain, that comes to about 24 inches of water.
On November 14 Collyer normally reaches 54° and falls to 28°. The record high is 75°, in 1962; the record low −5°, in 1940. The most rain on this date, 0.15 in, fell in 1993.
Normals 1991–2020 and records since 1893 at Quinter, 7 miles west-northwest. NOAA, through RCC-ACIS.
