Off-topic: Cross-Canada road trip #4

Lake of the Woods

Day 4 of the road trip: Kenora, ON to Sault Ste Marie, ON

Going even further afield than is usual for z=z for a brief lesson in physical geography, try this: Go to Google Maps and centre the map around the eastern half of Canada (Hudson Bay should be in the middle). Notice that Ontario, Quebec, Manitoba, the northern half of Saskatchewan and Nunavut are all liberally laced with blue? Now switch to ‘terrain’ view – see how all of this is a darker green than the south? This is the Canadian Shield, created during the Pleistocene when glaciation scraped it down to the 4.5 billion year old bedrock. Pockets in the newly-exposed granite filled up with rainwater to create hundreds of thousands of lakes; so many that when you fly over it, you can’t tell whether you are looking at lakes or islands. Today’s drive, along the north shore of Lake Superior, is in the heart of this geological region.

All of this is really by way of preamble to introduce Montreal’s Besnard Lakes, which is named after one of these glacial bodies of water.
