Established by W.H. Bates and D.T. Beals, Colorado merchants and ranchers on the Arkansas River since 1870. "Crowded conditions" there resulted in moving herd and brand to the Panhandle of Texas in 1877 -- three years after Indians were expelled from this region. LX cattle were being driven to Dodge City for shipment to market or to ranges in Montana and Wyoming as the buffalo were being exterminated in the area.
The ranch extended from present cities of Dumas (30 mi. N) to Amarillo (20 mi. S), and was 20 miles wide--1,000 square miles of open range. The ranch was sold in 1884 to the American Pastoral Company, Ltd., London. Ownership included 210,597 acres of land, 45,000 cattle and 1,000 horses. Famous LX cowboys included Allie Bates and John Ray, whose names are on geological maps, and Charles Siringo, author of Western Americana and Cattle Rustler Detective.
Potter County was organized on Aug. 30, 1887 by 53 qualified electors. By unanimous vote of the 38 LX cowboys, Amarillo was elected the county seat. In 1906 the Pastoral Company began liquidating. Heirs of large purchasers now own the properties.
