Waterways of the Canadian Shield
|
Geological processes, from the powerful movement of large blocks of the Earth's crust (called plates) to the erosional action of the glaciers, created our natural waterways and lakes. They were extensively used by our ancestors as transportation routes (or 'highways').
Pictographs
At least 23 reported sites from Uranium City to The Pas contain pictographs, drawn by our ancestors up to a thousand years ago.

Natural Highways
Northern rivers and lakes attract numerous tourists, anglers, and canoeists in the summer and become highways in the winter. The deep channels of our great rivers were cut by glacial runoff. These rivers are still used as 'water highways' today.
Waterways are a means of access to our continental interior (the Canadian Shield).
