Oil Seeps in Arizona
December 2003 by Edgar B. Heylmun, PhDCompared to California, Arizona has virtually no oil seeps. But, the great Permian Basin of West Texas has virtually none either. Arizona has something that neither California nor Texas have, and that is public lands that are open for leasing. The northern half of Arizona has more seeps and is thus of greater interest, but it would be foolish to disregard the southern half because giant oil and natural gas fields could underlie some of the broad desert valleys.
There is a sizable area that straddles the U.S.-Mexico border where native silver occurs in shear zones at relatively shallow depths. The district is in the low but rugged Pajarito Mountains, the highest point of which is 5,838 feet at Cerro Ruido, on the Mexican side. The deceptively rough terrain forced the first border surveyors, in 1855, to kill several mules and horses because of their injuries.
