75° on Nov. 16, 2016, the hottest reading for this week of the year since 1961. Next is 74° in 1999.
Genesee’s center stands about 7,730 ft above sea level. Within three miles the land runs from 6,530 ft to 8,010 ft, a difference of 1,480 ft: steep hill country. The highest named summit within 15 miles is Chief Mountain, about 11,660 ft, 13 miles west.
Under the town center the state geologic map shows Felsic and hornblendic gneisses, either separate or interlayered, from the Paleoproterozoic, 1.6 to 2.5 billion years old.
The section below crosses 7 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 4×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Biotite-gneiss, schist, migmatite. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 10 mi of the line.
Sandstone, mudstone, conglomerate. Age: Late Cretaceous to Paleocene, 56 to 100 million years old. About 7 mi of the line.
Gneiss. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 6 mi of the line.
Sandstone, shale, limestone. Age: Permian to Early Triassic, 247 to 299 million years old. About 0.8 mi of the line.
Arkose, conglomerate. Age: Carboniferous to Permian, 252 to 324 million years old. About 0.4 mi of the line.
Sandstone, shale, claystone. Age: Late Cretaceous, 66 to 100 million years old. About 0.3 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 1 smaller unit along the line are not listed.

A raindrop that lands in Genesee reaches the Gulf of America by way of Bear Creek, the South Platte, the Platte, the Missouri and the Mississippi: about 2,430 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 Genesee; river miles along the main stem, rounded.
Genesee has a warm-summer humid continental climate. Summer afternoons average 81° in July; winter nights fall to about 13° in January. A normal year brings about 81 inches of snow; with the rain, that comes to about 19 inches of water.
On November 14 Genesee normally reaches 52° and falls to 21°. The record high is 74°, in 1999; the record low −10°, in 2014. The most rain on this date, 1.35 in, fell in 1987.
Normals 1991–2020 and records since 1961 at Evergreen, 4 miles southwest, 730 ft lower. NOAA, through RCC-ACIS.
