76° on Nov. 12, 1973, the hottest reading for this week of the year since 1920. Next is 73° in 1967.
North Fork’s center stands about 6,840 ft above sea level. Within three miles the land runs from 6,130 ft to 7,300 ft, a difference of 1,170 ft: steep hill country. The highest named summit within 15 miles is McKays Peak, about 9,140 ft, 10 miles east-southeast.
Under the town center the state geologic map shows Oligocene to Paleocene[?] sedimentary rocks (conglomerate, sandstone), from the Early Paleocene to Early Oligocene, 30 to 65 million years old.
The section below crosses 5 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: Early Pliocene to Holocene, less than 4 million years old. About 7 mi of the line.
Sandstone, limestone. Age: Permian, 270 to 280 million years old. About 6 mi of the line.
Conglomerate, sandstone. Age: Early Paleocene to Early Oligocene, 30 to 65 million years old. About 5 mi of the line.
Sandstone, shale. Age: Late Cretaceous, 88 to 97 million years old. About 5 mi of the line.
Sandstone, shale, limestone. Age: Middle Pennsylvanian to Permian, 280 to 310 million years old. About 2 mi of the line.

A raindrop that lands in North Fork reaches the Gulf of California by way of the North Fork White, the White River, the Salt River, the Gila and the Colorado: about 560 river miles.
200 miles of the trip are on the Gila.
Often dry. About 40% of the way is mapped as streams that run only after rain or snowmelt; the water makes the whole trip in floods.
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 North Fork; river miles along the main stem, rounded.
North Fork has a warm-summer Mediterranean climate. Summer afternoons average 80° in June; winter nights fall to about 21° in January. A normal year brings about 66 inches of snow; with the rain, that comes to about 24 inches of water.
On November 14 North Fork normally reaches 55° and falls to 28°. The record high is 73°, in 1967; the record low 6°, in 1944. The most rain on this date, 1.15 in, fell in 1968.
Normals 1991–2020 and records since 1920 at Mcnary 2 N, 9 miles northeast, 500 ft higher. NOAA, through RCC-ACIS.
