chippewa falls
Chippewa Falls, are about 40 km north of Sault Ste. Marie. The falls, on Highway 17, mark the half way point of the Trans-Canada Highway.
The falls, on the Chippewa River, consist of an upper (7 metre height) and lower cascade (6 metre height)- -about 50 meters apart. The lower falls consist of 2.7 billion-year-old pink granite bedrock, partially covered by a 1.1 billion-year-old grey Keweenawan basalt lava flow from the Grenville orogeny (mountain building epoch). The upper falls were created by a vertical diabase dike cutting through the granite--then, a lateral fault cut the granite and basalt layers, lifted the dike 10 meters, creating the upper falls.
