−14° on Nov. 15, 1985, the coldest reading for this week of the year since 1891. Next is −13° in 1978.
Granger’s center stands about 6,270 ft above sea level. Within three miles the land runs from 6,230 ft to 6,420 ft, a difference of 190 ft: gently rolling country. The highest named summit within 15 miles is Wildcat Butte, about 6,980 ft, 12 miles south-southwest.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 33×. 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, claystone. Age: Eocene, 34 to 56 million years old. About 22 mi of the line.
Clay, silt, sand. Age: Pleistocene to Holocene, less than 2.6 million years old. About 2 mi of the line.
Sand, unconsolidated. Age: Pleistocene to Holocene, less than 2.6 million years old. About 0.4 mi of the line.

A raindrop that lands in Granger reaches the Gulf of California by way of the Blacks Fork, the Green River and the Colorado: about 1,520 river miles.
Lakes on the way: Lake Mead, Lake Powell, Flaming Gorge Reservoir and Lake Mohave.
410 miles of the trip are on the Green River.
Seldom reaches the sea. Dams and canals now take nearly all of the Colorado before its old delta in Mexico.

Granger has a cold semi-arid climate. Summer afternoons average 83° in July; winter nights fall to about 12° in December. A normal year brings about 31 inches of snow; with the rain, that comes to about 8 inches of water.
On November 14 Granger normally reaches 42° and falls to 22°. The record high is 65°, in 2025; the record low −8°, in 1985. The most rain on this date, 0.55 in, fell in 1988.
