The Bridge River site is a winter pithouse village near the confluence of the Bridge and Fraser Rivers in the Mid-Fraser Canyon that was occupied periodically from as early as 1800BP to the mid-19th century. Prentiss et al. (2008) divide the range of occupations into four Periods: Bridge River (BR) 1, c. 1800-1600BP, BR2, c. 1600-1300BP, a short-lived BR3, c. 1300-1100BP (by the end of this period the village appears to have been largely abandoned), and BR4, a late reoccupation of the site, c. ~500 to 100BP (Prentiss et al. 2008, 2011, 2012). During BR2 and into BR3, between 1500-1100BP, the village experienced punctuated population growth and then underwent dynamic and rapid population decline and abandonment at the end of BR3. This trend continued throughout the Middle Fraser region toward the end of BR3, as major village populations experienced rapid declines and abandonment events leading up to roughly 1000 BP.
