The Upper Fraser Historical Geography Project was conducted by UNBC faculty and a team of researchers between 1999 and 2002. The lead researchers were Aileen Espritiu, Gail Fondahl, Greg Halseth, Debra Straussfogel, and Tracy Summerville. The project resulted in the creation of 93 oral history records and their transcripts. Participants included regional forest industry executives, politicians (including former MLA Ray Williston, local mayors and Fraser Fort George Regional District representatives), forest industry workers, and former and contemporary Upper Fraser community residents. The oral histories document the rise, consolidation and demise of the forestry-based settlements along the Upper Fraser River between 1915 and 2000.
