The Kanarraville plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
78° on Nov. 13, 1967, the hottest reading for this week of the year since 1911. Next is 75° in 1956.
Kanarraville’s center stands about 5,570 ft above sea level. Within three miles the land runs from 5,340 ft to 7,820 ft, a difference of 2,480 ft: mountain country. The highest named summit within 15 miles is Black Mountain, about 10,370 ft, 13 miles east.
Under the town center the state geologic map shows Alluvium and colluvium (unconsolidated), from the Quaternary, less than 2.6 million years old.
The section below crosses 10 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.
Sandstone-mudstone, sandstone. Age: Late Cretaceous, 72 to 94 million years old. About 7 mi of the line.
Felsic-volcanic. Age: Late Oligocene to Middle Miocene, 12 to 28 million years old. About 5 mi of the line.
Quartz-monzonite. Age: Early Oligocene to Early Miocene, 16 to 34 million years old. About 3 mi of the line.
Unconsolidated. Age: Quaternary, less than 2.6 million years old. About 2 mi of the line.
Basalt. Age: Quaternary, less than 2.6 million years old. About 2 mi of the line.
Limestone, mudstone. Age: Late Paleocene to Early Oligocene, 28 to 59 million years old. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 4 smaller units along the line are not listed.

A raindrop that lands in Kanarraville reaches the Gulf of California by way of Ash Creek, the Virgin and the Colorado: about 630 river miles.
Lakes on the way: Lake Mead, Lake Mohave and Lake Havasu.
290 miles of the trip are on the Colorado.
Seldom reaches the sea. Dams and canals now take nearly all of the Colorado before its old delta in Mexico.

Kanarraville has a dry-summer hot-summer continental climate. Summer afternoons average 90° in July; winter nights fall to about 20° in December. A normal year brings about 38 inches of snow; with the rain, that comes to about 18 inches of water.
On November 14 Kanarraville normally reaches 56° and falls to 28°. The record high is 74°, in 1999; the record low 8°, in 2000. The most rain on this date, 1.97 in, fell in 1955.
