The scarping and gouging action of the ice created depressions in the bedrock. These depressions filled with water to form the hundreds of thousands of lakes that now dot the shield.
Glaciers can alter the drainage patterns of a shield by creating valleys and basins through erosion. As glaciers move, they carve out new paths for water to flow, influencing the direction and speed of drainage. Glacial meltwater can also interact with underlying soil and rocks, affecting groundwater movement and storage.
The effects of the mountain glaciers on Canada included beautiful formation of distinctive features such as cirques, icebergs, and deep gorges.
