Avon’s center stands about 7,450 ft above sea level. Within three miles the land runs from 7,330 ft to 9,770 ft, a difference of 2,440 ft: mountain country. The highest named summit within 15 miles is Mount of the Holy Cross, about 13,950 ft, 12 miles south.
The section below crosses 13 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.
Arkose, siltstone, conglomerate. Age: Carboniferous to Permian, 252 to 324 million years old. About 7 mi of the line.
Biotite-gneiss, schist, migmatite. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 6 mi of the line.
Sandstone, shale. Age: Carboniferous, 299 to 324 million years old. About 3 mi of the line.
Granite. Age: Paleoproterozoic, 1.6 to 2.5 billion years old. About 2 mi of the line.
Arkose, conglomerate, shale. Age: Carboniferous, 299 to 324 million years old. About 2 mi of the line.
Siltstone, shale. Age: Carboniferous, 299 to 324 million years old. About 1 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 7 smaller units along the line are not listed.

A raindrop that lands in Avon reaches the Gulf of California by way of Buck Creek, the Eagle and the Colorado: about 1,310 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.

Avon has a warm-summer humid continental climate. Summer afternoons average 77° in July; winter nights fall to about 7° in January. A normal year brings about 189 inches of snow; with the rain, that comes to about 22 inches of water.
On November 14 Avon normally reaches 38° and falls to 16°. The record high is 57°, in 1989; the record low −6°, in 2000. The most rain on this date, 0.58 in, fell in 2006.
Normals 1991–2020 and records since 1985 at Vail, 9 miles east, 850 ft higher. NOAA, through RCC-ACIS.
