The Cariboo region comprises that section of Central British Columbia between the Fraser river and the mountains of the N. Thompson river, extending northward from Clinton to Quesnel; through it the old Cariboo trail (now a motor road) passes and railway communication with the south is afforded by the P. G. & E. Ry. Its altitude is around 2500 ft. and it consists largely of rolling, wooded country interspersed with numerous lakes; in the southwest in the vicinity of Jesmond, Mt. Bowman, a northern spur of the mountains back of Lillooet, rises to a height of about 7500 ft. The summer rainfall is slight, and the area belongs in the so-called “dry belt”.
