Canelo Hills

The range consists of a series of northwest–southeast trending ridges extending from the Sonoita Creek valley southwest of Sonoita to the Parker Canyon Lake area in southwest Cochise County, Arizona.

The Canelo Hills merge with the Huachuca Mountains to the southeast.

The southwest margin extending toward the Patagonias is underlain by Cretaceous–Eocene volcanics.

This caldera is mapped as a kidney shaped feature stretching from just north of Canelo Pass some 15 miles (24 km) to the southeast into the Huachucas and underlying the eastern portion of the San Rafael Valley.

[2] The Jurassic volcanics in the area consist of rhyolite welded tuff containing large exotic blocks of limestone, quartzite and other rock types interpreted as "intercaldera megabreccia lenses".
