Kakabeka Falls Provincial Park and Mount McKay
Kakabeka Falls are massive. Dropping 130 feet, The Kaminiquistia River barrels over the Precambrian chert caprock and down the gorge at an average rate of 1,800 cubic feet per second here, eroding the soft shale underneath the falls and along the gorge walls with incredible force. The morning we arrived they had released a dam upriver and flow was estimated at over 10,500 cubic feet per second, which was impressive to even the employees we spoke to. In addition to the falls, the park also protects some of the oldest fossils in the world – rare stromatolites, which are 2 billion year old fossilized blue-green algae found in the chert. Growing in shallow seas, the algae would settle on top of each other in columnar patterns; when the rock is cross-sectioned, the columns produce amazing patterns.
While stopping in the Thunder Bay area we also took a drive up Mount McKay that provides overlooks onto the city of Thunder Bay and Lake Superior:
