to be crossed, The area is heavily forested below 5,000 feet in elevation with spruce, balsam, jack pine, and poplar. Trout and whitefish occur abundantly in all the lakes, and salmon are found in Babine Lake, Moose, deer, and black bear are plentiful. Game birds to be found are grouse and ptarmigan, The only settlements within the area are the Indian villages of Donald Landing, Babine Portage, Nacocochie (Stuart Portage), and Middle River, and except for a few white settlers on Babine Lake there are no other inhabitants, Normally, prospecting could be carried on from the middle of April to the middle of October, but during the rest of the year the snowfall is too heavy and the temperature too low. The first geological mapping of any part of the area was done in 1879 by G.M. Dawson, who made an exploration survey along Babine and Stuart Lakes-, In 1915 a reconnaissance survey was made Se re ar ee rE ES eee la pees Report on an Exploration from Port Simpson on the Pacific Coast to Edmonton on the Saskatchewan Embracing a Portion of the Northern Part of British Columbia and Peace River Country; Geol.
