The soil study was carried out at three locations along the Mackenzie<br />
River during the 1972 field season (see Figure 1) .<br />
During the G .S .C . helicopter survey the following map areas were<br />
covered - The Fort Liard Sheet (N .T .S . 95B), Sibbeston Lake Sheet<br />
(N .T .S . 95G), Kakisa River Sheet (N .T .S . 85D), Bulmer Lake Sheet<br />
(N .T .S . 951), Wrigley Sheet (N .T .S . 950) and Dahadinni River Sheet<br />
(N .T .S . 95N) . The Fort Simpson (N .T .S . 95H) and Mills Lake (N .T .S . 85F)<br />
sheets along the Mackenzie and Liard Highways were checked and the<br />
Trout Lake Sheet (N .T .S . 95A), Camsell Bend Sheet (N .T .S . 95J) and<br />
Root"River Sheet (N .T .S . 95K) were interpreted by means of work done<br />
in adjacent areas .<br />
During the investigations with Canadian Forestry Service<br />
personnel,<br />
areas around both Norman Wells and north of Inuvik were<br />
covered . The former included the area from Fort Norman north to<br />
Sans Sault Rapids and west to the Mackenzie Mountains, and the latter<br />
extended to Richards Island, Tuktoyaktuk and the Eskimo Lakes .<br />
