−11° on Nov. 13, 2014, the coldest reading for this week of the year since 1996. Next is 2° in 2019.
Wiley’s center stands about 3,740 ft above sea level. Within three miles the land runs from 3,680 ft to 3,910 ft, a difference of 230 ft: rolling country.
Under the town center the state geologic map shows Carlile Shale, Greenhorn Limestone, and Graneros Shale (shale, limestone), from the Early Cretaceous to Late Cretaceous, 66 to 145 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 31×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Shale. Age: Late Cretaceous, 66 to 100 million years old. About 11 mi of the line.
Shale, limestone. Age: Early Cretaceous to Late Cretaceous, 66 to 145 million years old. About 7 mi of the line.
Unconsolidated. Age: Quaternary, less than 2.6 million years old. About 5 mi of the line.
Sand, silt. Age: Quaternary, less than 2.6 million years old. About 0.5 mi of the line.
Gravel, unconsolidated. Age: Pleistocene, less than 0.5 million years old. About 0.4 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.

A raindrop that lands in Wiley reaches the Gulf of America by way of the Arkansas and the Mississippi: about 1,710 river miles.
Lakes on the way: Murray Lake and Ozark Lake.
810 miles of the trip are on the Arkansas.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Wiley; river miles along the main stem, rounded.
Wiley has a cold semi-arid climate. Summer afternoons average 96° in July; winter nights fall to about 14° in January. About 13 inches of rain fall in a normal year.
