69° on Nov. 11, 1973, the hottest reading for this week of the year since 1900. Next is 67° in 1967.
Telluride’s center stands about 8,770 ft above sea level. Within three miles the land runs from 8,680 ft to 12,910 ft, a difference of 4,230 ft: mountain country. The highest named summit within 15 miles is Mount Wilson, about 14,100 ft, 12 miles southwest.
Under the town center the state geologic map shows Cutler Fm (arkose, siltstone, conglomerate), from the Permian, 252 to 299 million years old.
The section below crosses 11 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 3×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Unconsolidated. Age: Quaternary, less than 2.6 million years old. About 5 mi of the line.
Andesite. Age: Late Eocene to Early Oligocene, 30 to 35 million years old. About 5 mi of the line.
Shale, sandstone. Age: Early Cretaceous to Late Cretaceous, 66 to 145 million years old. About 5 mi of the line.
Mafic-hypabyssal, felsic-hypabyssal. Age: Eocene to Miocene, 5.3 to 56 million years old. About 3 mi of the line.
Unconsolidated. Age: Pleistocene, less than 0.5 million years old. About 2 mi of the line.
Sandstone, mudstone, claystone. Age: Late Jurassic, 145 to 164 million years old. About 0.9 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 5 smaller units along the line are not listed.

A raindrop that lands in Telluride reaches the Gulf of California by way of Cornet Creek, the San Miguel, the Dolores and the Colorado: about 1,230 river miles.
Lakes on the way: Lake Mead, Lake Powell, Lake Mohave and Lake Havasu.
Seldom reaches the sea. Dams and canals now take nearly all of the Colorado before its old delta in Mexico.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Telluride; river miles along the main stem, rounded.
Telluride has a warm-summer humid continental climate. Summer afternoons average 77° in July; winter nights fall to about 0° in January. A normal year brings about 131 inches of snow; with the rain, that comes to about 20 inches of water.
On November 14 Telluride normally reaches 46° and falls to 13°. The record high is 67°, in 1999; the record low −9°, in 1915. The most rain on this date, 0.47 in, fell in 2004.
Normals 1991–2020 and records since 1900 at Telluride 4 WNW, 3 miles west-northwest, 120 ft lower. NOAA, through RCC-ACIS.
