Tethul

North of Lake Athabasca, the Tethul River drains a country of flat ground and many small lakes. Its Dene name belongs to a waterway that joins the Taltson River on its journey toward Great Slave Lake. The basin lies near the edge of the Canadian Shield, where thin glacial deposits cover ancient rock. Lakes and channels break up the northern forest, providing a landscape of connected waters rather than a single open plain.
