during its 22-year operating life. Since the mine is now closed and decommissioned, there are no travel services in the vicinity and no functional airstrip. Motorists driving to the structure need to carry sufficient fuel and supplies for the round trip back to La Loche.

In the northern part the rim is visible as a series of low hills, in the southern part it is indicated by the course of Douglas River. Carswell Lake (in the upper right) cuts into the structure.
