Like much of northern Ontario, the park contains geological reminders of a time long past such as eskers and kettle lakes. As the glaciers of the last Ice Age melted, about 10,000 years ago, tunnels were formed by waters flowing under the decaying ice. Debris eventually filled those tunnels, which became eskers -- steep-sided ridges of sand and gravel.

Deep, round lakes called kettle lakes were formed when large blocks of ice were buried by the collapse of overlying sediments that delayed the melting action. The ice made deep depressions in the sandy soil, which later filled with water as the ice melted, forming small lakes. Several of the park's 26 lakes are kettle lakes.

Trees in the park are typical of the northern boreal forest, with birch, aspen, spruce and balsam fir predominating.
There are many small fur-bearing mammals in the park, including beaver, muskrat, otter, marten, fox, ermine, mink, fisher and chipmunk. Moose and bear also make their home in the area, and the occasional wolf howl is heard at night.
