Volume 3 in the history of the North Trail from New Mexico to Northern Alberta, covering the 30 years (1 generation) from 1820-1850. This period saw changes along the north trail that set the stage for the history of Alberta and western Canada as we know it - thanks to the unexpected results of an action by the Hudson's Bay Company. Blackfoot power and dominance began to subside in both the north and south of the trail, while the Mountain Cree now became the dominant group along the northern portion of the trail and in adjacent areas of British Columbia, Montana and Idaho. At the same time the Iroquois freemen, scattered from Lesser Slave Lake to Utah, became fully integrated into the Cree. Though the Blackfoot continued to be prominent and dominant in both north and south, culturally the area was now divided into the violent and hostile south and the relatively peaceful north. Throughout this area a rudi-mentary Postal service now connected the far-flung Cree. 522 pages.
