75° on Nov. 17, 2016, the hottest reading for this week of the year since 1940. Next is 73° in 2005.
Genoa’s center stands about 5,600 ft above sea level. Within three miles the land runs from 5,330 ft to 5,630 ft, a difference of 300 ft: rolling country.
Under the town center the state geologic map shows Ogallala Fm (sandstone, conglomerate), from the Miocene to Pliocene, 2.6 to 23 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 33×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sandstone, conglomerate. Age: Miocene to Pliocene, 2.6 to 23 million years old. About 16 mi of the line.
Shale. Age: Late Cretaceous, 66 to 100 million years old. About 8 mi of the line.

A raindrop that lands in Genoa reaches the Gulf of America by way of Hell Creek, the Arikaree, the Republican, the Kansas, the Missouri and the Mississippi: about 2,280 river miles.
Lakes on the way: Harlan County Lake and Swanson 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 Genoa; river miles along the main stem, rounded.
Genoa has a cold semi-arid climate. Summer afternoons average 86° in July; winter nights fall to about 20° in February. A normal year brings about 35 inches of snow; with the rain, that comes to about 16 inches of water.
