Abstract Geophysical evidence indicates that the delta area of the Mackenzie River, Northwest Territories, is affected by tectonic subsidence. Pingos are of sparse occurrence in the Arctic as a whole but they occur in hundreds in the Mackenzie River delta. In a region of subsidence, as recent sediments pass through the base of permafrost, compaction becomes possible. The resulting water expulsion produces an artesian head responsible for building pingos.

A palaeobotanical and palynological study of samples of buried peat from the MacKenzie River delta area, Northwest Territories, has shown that the peat accumulated during an interglacial interval. For reference purposes a study of modern pollen of Rubus chamaemorus L. and of four species of Drosera L. has been made.

Although the American Philosophical Society–University of New Mexico Mackenzie Valley Expedition of 1938 (Bliss, 1939, p. 365) was not primarily concerned with Eskimo archaeology, the members felt, while at the trading rendezvous Aklavik on the lower Mackenzie River, that the opportunity to run down to the Arctic coast was too obvious to be neglected. The archaeology of the Western Eskimo of the Mackenzie area has never been well studied; little, as a matter of fact, has been added since 1930 when Mathiassen wrote the introduction to his Western Eskimo report. This paper will add somewhat to a meager store of fact.
