The Beyond Sand Creek documentary is about the Arapaho tribal efforts to reverse assimilation by teaching traditional culture and undoing negative tribal stereotypes in the Boulder Valley. The documentary integrates the story of Fort Chambers, a fort constructed on the east edge of Boulder where the Third Colorado Cavalry troops were trained to ambush Arapaho and Cheyenne at the Sand Creek Massacre in Southeast Colorado. The Arapaho are working with public and private officials to return their traditional homeland to the tribe. We interviewed several tribal members from Oklahoma and Wyoming over the course of several years to learn their perspectives about racial discrimination that arose from the western expansion of settlers occupying tribal land.
