83° on Nov. 14, 2025, the hottest reading for this week of the year since 1894. Next is 81° in 1999.
Blue Hill’s center stands about 1,970 ft above sea level. Within three miles the land runs from 1,890 ft to 2,010 ft, a difference of 120 ft: gently rolling country.
Under the town center the state geologic map shows Ogallala Group or Formation (siltstone-mudstone, conglomerate-sandstone), from the Miocene, 5.3 to 23 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 62×. 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 12 mi of the line.
Limestone, shale. Age: Late Cretaceous, 66 to 100 million years old. About 11 mi of the line.
Shale. Age: Late Cretaceous, 66 to 100 million years old. About 0.7 mi of the line.

A raindrop that lands in Blue Hill reaches the Gulf of America by way of Ash Creek, the Little Blue, the Big Blue, the Kansas, the Missouri and the Mississippi: about 1,920 river miles.
Lake on the way: Tuttle Creek 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 Blue Hill; river miles along the main stem, rounded.
Blue Hill has a hot-summer humid continental climate. Summer afternoons average 88° in July; winter nights fall to about 16° in January. About 26 inches of rain fall in a normal year.
On November 14 Blue Hill normally reaches 52° and falls to 29°. The record high is 83°, in 2025; the record low −7°, in 1940. The most rain on this date, 1.20 in, fell in 1926.
