Settled in 1885 and named for a marker at the springs a few miles west, Monument remained a ranching community until oil was discovered in 1928. The Indian statue, called Geronimo by residents, was erected in 1928 by land developers. Monument has produced 4 world champion rodeo performers: George Weir & Roy, Betty Gayle & Jimmie B. Cooper. A centennial celebration was held in 1985.
