Monahans, Ward County
A project of the Shell Oil Company, the construction of this oil storage tank in 1928 was the result of an oil boom in the area. Built to accommodate crude oil until it could be shipped to refineries, the tank was constructed by crews working on a 24-hour schedule using hand operated and horse-drawn equipment. Covering eight acres of land, the tank was able to hold over one million barrels of oil. It was filled to capacity only once. Efforts to convert it into a water-filled recreation center in the 1950s were unsuccessful, and it became a museum in 1986.
