94° on Nov. 15, 1990, the hottest reading for this week of the year since 1898. Next is 84° in 1999.
Bartley’s center stands about 2,350 ft above sea level. Within three miles the land runs from 2,300 ft to 2,490 ft, a difference of 190 ft: gently rolling country.
Under the town center the state geologic map shows Niobrara Formation (limestone, shale), from the Late Cretaceous, 66 to 100 million years old.
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 57×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Siltstone-mudstone, conglomerate-sandstone. Age: Miocene, 5.3 to 23 million years old. About 22 mi of the line.
Limestone, shale. Age: Late Cretaceous, 66 to 100 million years old. About 3 mi of the line.

A raindrop that lands in Bartley reaches the Gulf of America by way of the Republican, the Kansas, the Missouri and the Mississippi: about 2,030 river miles.
Lake on the way: Harlan County Lake.
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 Bartley; river miles along the main stem, rounded.
Bartley has a hot-summer humid continental climate. Summer afternoons average 90° in July; winter nights fall to about 13° in January. A normal year brings about 24 inches of snow; with the rain, that comes to about 23 inches of water.
On November 14 Bartley normally reaches 55° and falls to 23°. The record high is 91°, in 1990; the record low −8°, in 1986. The most rain on this date, 1.21 in, fell in 1926.
Normals 1991–2020 and records since 1898 at Cambridge, 9 miles east-northeast. NOAA, through RCC-ACIS.
