Why Northern Ontario Is Sitting On The Most Valuable Land In Canada's History So Far

I taught geography for 40 years, and Northern Ontario still gives me some of my favourite stories. Join me as I count down 25 facts about the Canadian Shield, Lake Superior and the mining towns built on the riches beneath them. I follow Apollo astronauts to Sudbury, trace a vanished lake that helped cool the northern hemisphere, and tell the story of a gold fortune that ended in an unsolved murder. At the end, we head deep beneath Timmins to water sealed in the rock for at least two billion years.
