> A prehistoric structure reminiscent of England’s iconic Stonehenge has been uncovered in Grand Traverse Bay, an arm of Lake Michigan on the western shore of Michigan’s Lower Peninsula.
> ... discovered what appears to be a dry land corridor that once connected northeast Michigan and southern Ontario. Scientists say the main feature, known as Drop 45 Drive Lane, is the most complex hunting structure discovered beneath the Great Lakes to date. The 9,000-year-old limestone structure consists of two parallel lines of stones that lead to a cul-de-sac lined with natural cobblestones. If the findings are correct, the hunting complex would be twice as old as Stonehenge.
Toronto and Kitchener-Waterloo are both healthy, vibrant startup hubs, but are distinct regions IMO. They are 120km apart and it takes ~90min to drive from Communitech to MARS https://goo.gl/maps/vRJqc7JsNcp.
Both positively influence each other, compete for resources. Waterloo has some more affordable suburban housing, and less vibrant city/'downtown'. Toronto is more expensive, is bigger and better in many respects.
Vancouver and Montreal are also decent startup ecosystems. I've been writing a researching Canadian cities/startup ecosystems for a book. Lots of stats and resources here if you're really into this topic: https://github.com/DeBraid/ham-innov-essay
This is literally the purpose of a stone wall: herding the animals in a specific direction, to a specific location.

Because 8500 years ago hunting tools were primitive (stone tips on spears) so stacking the odds in their favour was smart.
