Exploring Canada's unmapped rivers

Humans have been exploring far-off lands for milleniums now. And while it may seem that unknown parcels of land are few and far between, one young explorer has set out to discover parts of Canada that remain unmapped.

Adam Shoalts has just returned from an expedition on the Again River, which runs just south of Hudson Bay. He set out with the help of the Royal Canadian Geographical Society to gather pictures and descriptions of the many rapids and waterfalls along the river, not shown on existing topographical maps. Shoalts joined us on the line this morning from St-Catherines, Ontario.
