Grayhorse is eight miles southeast of Fairfax. Grayhorse is one of the Osage Indian Villages in Osage County
In the mid 1880's the Osage at Gray Horse received the I'n-lon-schka dance, traditions, and drum from the Ponca Indians. In 1908 the Osage built a round house to hold ceremonies and later constructed a Native American Church. In the spring of 1963, a prairie fire destroyed both structures. In 1964, new structures were erected to ensure the continuance of the I'n-lon-scka.
