Tent Mountain
Tent Mountain is located on the border of Alberta and British Columbia on the Continental Divide. It was named in 1911 by Morrison P. Bridgland.
Tent Mountain hosts a legacy mountaintop removal coal mine, which closed in 1983. Approximately half of the "top" of Tent Mountain was removed to access the coal creating a large open-pit at the top of the mountain. The waste rock was left in a pile along the side of the mountain next to the open-pit. In 2021, a proposal was received to restart mining at the top of Tent Mountain. The proposal has since been withdrawn.
A recent study of water quality both within the mine area and in rivers draining the mine revealed elevated concentrations of selenium. Selenium concentrations downstream of Tent Mountain reached 185 μg/L in a pond below the mine spoil pile, and up to 23 μg/L in Crowsnest Creek, which drains the pond and the mine property. Crowsnest Creek in turn flows into Crowsnest Lake.
