Another spectacular natural landscape in Western Ontario is Ouimet Canyon, about an hour northeast of Thunder Bay, off Highway 17. Steep-walled and narrow, the Canyon protects Arctic plants that were established in its chilly, shaded base during the Pleistocene Epoch (2 million to 10,000 years ago).
The Ouimet Canyon walls are composed of diabase, about 1 billion years old, that was apparently compressed and cracked by the Pleistocene glaciers, triggering an erosive process that has included the intrusion of glacial meltwater, freeze-thaw cycles and rock falls. Of course, such gradual erosion continues today.
A fine loop trail leads visitors from the parking lot out to two overlook decks that extend beyond the Canyon walls; watch for ruffed grouse in the woodlands during your hike. We highly recommend a visit to Ouimet Canyon Provincial Park for those traveling through this region of Ontario.
