South Komelik’s center stands about 2,560 ft above sea level. Within three miles the land runs from 2,390 ft to 2,780 ft, a difference of 390 ft: rolling country. The highest named summit within 15 miles is Baboquivari Peak, about 7,360 ft, 11 miles east-northeast.
Under the town center the state geologic map shows Quaternary surficial deposits, undivided (sand, silt, clay), from the Pleistocene to Holocene, less than 2 million years old.
The section below crosses 4 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 4×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sand, silt, clay. Age: Pleistocene to Holocene, less than 2 million years old. About 18 mi of the line.
Gravel, sand. Age: Late Pliocene to Pleistocene, 0.8 to 3 million years old. About 3 mi of the line.
Diorite, alkali-granite, granodiorite. Age: Early Jurassic to Late Jurassic, 150 to 180 million years old. About 3 mi of the line.
Rhyolite, sandstone, conglomerate. Age: Early Jurassic to Late Jurassic, 160 to 200 million years old. About 0.8 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.
