The name dates back to the 1860's. In 1858 William Oury bought cattle from a drover headed for California. Later Oury brought in 400 blooded Kentucky cattle and transferred his herd to Tanque Verde where he had a ranch. Two or more fairly large water holes containing green algae are the source of the name. The holes are at the base of Tanque Verde Ridge, a northwestern extension of the Rincon Mountains.
