The Dempster Highway, NWT Highway 8, crosses the Mackenzie River at Tsiigehtchic.[4] During winter, vehicle traffic is over the ice, during the rest of the year, traffic is carried by the ferry MV Louis Cardinal.
The ferry stops at Tsiigehtchic, on the eastern bank of the Arctic Red River, and on the southwestern and northeastern banks of the Mackenzie River, connecting the two legs of the Dempster Highway. The community is one of the few in the NWT not to be served by a permanent airport.
In early September 2007, near Tsiigehtchic, local resident Shane Van Loon discovered a carcass of a steppe bison, which was radiocarbon dated to c. 13,650 cal BP. This carcass appears to represent the first Pleistocene mummified soft tissue remains from the glaciated regions of northern Canada.[5]
