Gray Horse, Oklahoma
Gray Horse is an unincorporated community in Osage County, Oklahoma, United States. Its post office operated from May 5, 1890, to December 31, 1931. The town is named after Gray Horse (Ko-wah-hos-tsa), an Osage medicine man.
Along with nearby Fairfax and Pawhuska, Gray Horse played a role in the Osage murders of the early 1920s. Oil wealth in the area brought great riches to some Osage residents, but also violent crime. The story of these events is told in David Grann’s 2017 book Killers of the Flower Moon: The Osage Murders and the Birth of the FBI. Grann described Gray Horse as one of the older settlements in the Osage Nation.
Gray Horse is served by Woodland Public Schools. The Works Progress Administration built a public school there in 1939, which closed in 1963. In 2019 the Osage Nation acquired the school building. There is a fire department in Gray Horse.
Geography and basics: Gray Horse lies in the Central Time Zone. It sits at an elevation of about 922 feet (281 meters).
