Diamond A Cattle Company.

The Diamond A Cattle Company was a nationally-known ranching outfit based in New Mexico and Colorado between 1885 and 1939. The company was created in 1885 by Frank G. Bloom of Trinidad, Colorado, and M.D. Thatcher of Pueblo, CO, as a subsidiary operation to the Bloom Land and Cattle Company. At that time, The Bloom Land and Cattle Company acquired the Diamond A Ranch in Chaves County, New Mexico and the Circle Diamond Ranch in Lincoln County, N.M., combining the two ranches into a large cattle and sheep ranching outfit called the Diamond A Cattle Company. The daily operations of the Diamond A properties were managed by former Arizona Ranger and U.S. Army Captain, Burton C. Mossman of Roswell, N.M. After 1939, the Diamond A Cattle Company holdings were broken up into smaller parcels and sold. Leon E. Williams, New York businessman, acquired the Wagon Mound and South Dakota ranches. Other parcels were sold to parties in Roswell, New Mexico. By 1977, much of the Diamond A land in New Mexico was owned by Robert O. Anderson, Arco oil tycoon.
