Faunal material are compared from three different kinds of Late Precontact to Fur Trade Period houses on the Nechako Plateau of British Columbia.  These structures include a pithouse, two semi-subterranean houses, and a house built at ground level, each having different heating and lighting needs.  Calcined bone is common in each assemblage, reflecting attitudes towards the proper treatment of animal remains, but bones of this condition dominate the pithouse assemblage.  The role that light cast from burning bone plays in dark living spaces is discussed with reference to the archaeological literature from different spatial and temporal contexts.  It is argued that considering the light cast from burning bone, especially from beavers in the case of the pithouse examined here, helps to conceptualize how people navigated and embodied dark spaces and extends the importance of their relationship to animals beyond material consumption.
