| | THE GLACIAL LAKE AGASSIZ--Chapter II |
 | | The glacial Lake Agassiz was gradually reduced in size, first by the lowering of its southward outlet, and afterwards by finding successively lower outlets to the northeast, until, with the complete departure of the ice-sheet it shrank to its present representatives, the great lakes of Manitoba. |
 | | Rock Lake and Swan Lake, on this part of the river, each several miles long and from a half mile to 1 mile wide, are due to deposits brought into this valley by tributaries after it ceased to be the avenue of drainage from the Souris [p.58] basin. |
 | | Lake Agassiz thus received the waters of the upper Churchill, and of the basins of the Athabasca and Peace rivers, the great head streams of the Mackenzie; [p.64] and the Churchill, and probably also the upper Mackenzie basin, continued to be tributary to this lake through all its lower stages of outflow to Hudson Bay. |
