Burnham was born on aDakota SiouxIndian reservation in Minnesota, in the small village of Tivoli near the city of Mankato; there he learned the ways ofNative Americans as a boy. By the age of 14, he was supporting himself in California, while also learning scouting from some of the last of the cowboys and frontiersmen of theAmerican Southwest. Burnham had little formal education, never finishing high school. After moving to theArizona Territory in the early 1880s, he was drawn into thePleasant Valley War, a feud between families of ranchers and sheepherders.
