The Study Area

The four ASTt collections described herein were found in the southwest Anderson Plain, a portion of the lower Mackenzie Valley of the Northwest Territories bounded on the south by the Mackenzie River, on the east by the Anderson River, on the north by the Eskimo Lakes and Liverpool Bay, and on the west by the Mackenzie Delta.

The area is marked by moderate relief, rolling hills and numerous large lakes. These water bodies form the headwaters of secondary drainage systems which lead north to the Beaufort Sea (Kugaluk River), east to the Anderson River (Wolverine and Carnwath Rivers), and south and east to the Mackenzie River (Travaillant and Rengleng Rivers).

Three of the four ASTt assemblages were found on Hyndman Lake, the headwater lake of the east-flowing Wolverine River. The fourth ASTt-yielding site is the complex Vidiitshuu site on Vidiitshuu or Trout Lake, the headwater lake of the north-flowing Kugaluk River. These two water bodies lie within 50 km of each other.

The area is today well within the limits of the boreal forest, albeit one characterized as an open spruce-lichen forest. The faunal resources found here reflect the ecotonal situation it occupies. There are good fisheries of whitefish, lake trout and pike. The lakes are used as staging areas for migrating waterfowl, especially in the spring). A wide variety of mammals provide ample supplies of food and furs. The area today supports both woodland caribou and wintering members of the Bluenose barrenlands caribou herd. Moose are also found and have been present here for at least the last 6 centuries (Pilon 1989: 30).
