3.10 inches of rain fell in two days, the most for this week of the year since records began in 1952. The next wettest, 1.33 inches, fell in 1959.
Kino Springs’s center stands about 4,000 ft above sea level. Within three miles the land runs from 3,660 ft to 4,820 ft, a difference of 1,160 ft: steep hill country. The highest named summit within 15 miles is Mount Washington, about 7,170 ft, 5 miles east.
Under the town center the state geologic map shows Pliocene to middle Miocene deposits (conglomerate, sandstone), from the Early Miocene to Pleistocene, 2 to 16 million years old.
The section below crosses 5 rock units mapped at the surface.

Conglomerate, sandstone. Age: Early Miocene to Pleistocene, 2 to 16 million years old. About 12 mi of the line.
Conglomerate, sandstone. Age: Early Oligocene to Late Miocene, 11 to 32 million years old. About 5 mi of the line.
Granite, granodiorite, diorite. Age: Late Cretaceous to Early Eocene, 50 to 82 million years old. About 4 mi of the line.
Rhyolite, sandstone, conglomerate. Age: Early Jurassic to Late Jurassic, 160 to 200 million years old. About 2 mi of the line.
Diorite, alkali-granite, granodiorite. Age: Early Jurassic to Late Jurassic, 150 to 180 million years old. About 1 mi of the line.
