The Oak Springs 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.
2° on Nov. 12, 2000, the coldest reading for this week of the year since 1973. Next is 2° in 2018.
Oak Springs’s center stands about 6,580 ft above sea level. Within three miles the land runs from 6,470 ft to 7,350 ft, a difference of 880 ft: hilly country. The highest named summit within 15 miles is Torrivio Mesa, about 7,040 ft, 15 miles east.
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 12×. 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, siltstone. Age: Early Jurassic to Late Jurassic, 160 to 180 million years old. About 12 mi of the line.
Conglomerate, sandstone. Age: Late Triassic, 210 to 230 million years old. About 6 mi of the line.
Sandstone, limestone. Age: Permian, 270 to 280 million years old. About 3 mi of the line.
Mudstone. Age: Late Triassic, 210 to 230 million years old. About 3 mi of the line.
Sandstone, shale, limestone. Age: Middle Pennsylvanian to Permian, 280 to 310 million years old. About 0.4 mi of the line.

A raindrop that lands in Oak Springs reaches the Gulf of California by way of Black Creek, the Puerco, the Little Colorado and the Colorado: about 1,040 river miles.
Lakes on the way: Lake Mead, Lake Mohave and Lake Havasu.
290 miles of the trip are on the Colorado.
Often dry. About 30% of the way is mapped as streams that run only after rain or snowmelt; the water makes the whole trip in floods.

Oak Springs has a cold semi-arid climate. Summer afternoons average 89° in July; winter nights fall to about 14° in January. A normal year brings about 34 inches of snow; with the rain, that comes to about 11 inches of water.
On November 14 Oak Springs normally reaches 56° and falls to 20°. The record high is 73°, in 1999; the record low 4°, in 2000. The most rain on this date, 0.44 in, fell in 1997.
