3.66 inches of rain fell in two days, the most for this week of the year since records began in 1897. The next wettest, 3.02 inches, fell in 1978.
Williams’s center stands about 6,970 ft above sea level. Within three miles the land runs from 6,710 ft to 8,110 ft, a difference of 1,400 ft: steep hill country. The highest named summit within 15 miles is Sitgreaves Mountain, about 9,380 ft, 12 miles east-northeast.
Under the town center the state geologic map shows Pliocene to late Miocene basaltic rocks, from the Late Miocene to Early Pliocene, 4 to 8 million years old.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 8×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Basalt. Age: Late Miocene to Early Pliocene, 4 to 8 million years old. About 10 mi of the line.
Basalt. Age: Early Pliocene to Holocene, less than 4 million years old. About 9 mi of the line.
Sand, silt, clay. Age: Pleistocene to Holocene, less than 2 million years old. About 2 mi of the line.
Rhyolite, dacite, andesite. Age: Middle Miocene to Pleistocene, 2 to 12 million years old. About 2 mi of the line.

A raindrop that lands in Williams reaches the Gulf of California by way of Cataract Creek, Havasu Creek and the Colorado: about 760 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.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Williams; river miles along the main stem, rounded.
Williams has a warm-summer Mediterranean climate. Summer afternoons average 84° in July; winter nights fall to about 21° in December. A normal year brings about 65 inches of snow; with the rain, that comes to about 22 inches of water.
On November 14 Williams normally reaches 56° and falls to 28°. The record high is 74°, in 1933; the record low 0°, in 1930. The most rain on this date, 1.00 in, fell in 1955.
