76° on Nov. 15, 1999, the hottest reading for this week of the year since 1917. Next is 75° in 1941.
Sandy’s center stands about 4,790 ft above sea level. Within three miles the land runs from 4,380 ft to 5,300 ft, a difference of 920 ft: steep hill country. The highest named summit within 15 miles is Twin Peaks, about 11,430 ft, 10 miles east.
The section below crosses 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 3×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Clay. Age: Pleistocene, less than 2.6 million years old. About 10 mi of the line.
Unconsolidated. Age: Quaternary, less than 2.6 million years old. About 6 mi of the line.
Granodiorite. Age: Middle Eocene to Early Oligocene, 30 to 42 million years old. About 5 mi of the line.
Unconsolidated. Age: Pleistocene, less than 2.6 million years old. About 2 mi of the line.
Carbonate, shale. Age: Middle Cambrian, 497 to 521 million years old. About 0.9 mi of the line.
Dolostone. Age: Early Devonian to Late Devonian, 359 to 422 million years old. About 0.8 mi of the line.

A raindrop that lands in Sandy reaches Great Salt Lake by way of the Jordan: about 30 river miles. Great Salt Lake has no outlet to the sea: the water leaves only by evaporating or soaking into the ground.

Sandy has a dry-summer hot-summer continental climate. Summer afternoons average 91° in July; winter nights fall to about 23° in January. A normal year brings about 82 inches of snow; with the rain, that comes to about 24 inches of water.
On November 14 Sandy normally reaches 50° and falls to 32°. The record high is 70°, in 1990; the record low 13°, in 1978. The most rain on this date, 1.39 in, fell in 1955.
Normals 1991–2020 and records since 1917 at Cottonwood Weir, 5 miles northeast, 200 ft higher. NOAA, through RCC-ACIS.
