Gray Horse, Oklahoma
Gray Horse is a small unincorporated community in Osage County, Oklahoma. The post office was established May 5, 1890, and discontinued December 31, 1931. It was named for Gray Horse, an Osage medicine man.
Gray Horse and the surrounding towns of Fairfax, Oklahoma and Pawhuska, Oklahoma feature prominently in the Osage Murders, which took place in the early 1920s. The towns had grown exceedingly wealthy due to the discovery and drilling of nearby oil fields, and the resident Osage tribe members began to live lifestyles that befitted their newly acquired economic status. This time period and the circumstances and effects of the murders on the community of Gray Horse have been documented in David Grann's recent book .
