Yosemite's Buffalo Soldiers highlights the work of Yosemite ranger Shelton Johnson and his rediscovery of the story of the African American soldiers who patrolled the parks of the High Sierra at the turn of the last century. Shelton tells the story in the dramatis personae of a Buffalo Soldier himself, directly engaging visitors in a way that is immediate and often high impact.
