Figure 1: The High Level , Alberta, Beaver Landscape is one of most extensive landscapes with dominant impact of beavers on the drainage systes. This low resolution Google Earth (Digital Globe) image shows within the red polygone, an unusually high concentration of the beaver dams in in all the drainage channels. All the creeks (Bede, Caribou, Parma, Melto etc.) have been transformed by beaver into a long strips of beaver ponds and beaver controlled lakes. The Makenzie Highway is visible running North south in the right hand side of the image.
Figure 2: The NASA Landsat image (source Worl Wind 2000 coverage) with its greater sensitivity to water gives an even stronger impression of the number of lakes and ponds build and controled by beaver.
Figure 3: This high resolution Google Earth image shows clearly the beaverponds and lodges and the control of beaver of the streams. This is an enlargement of the area marked by the yellow circle in Figure 1.
Figure 4: This map from the 1915 edition of the National Atlas of Canada shows that the beaver landscape identified with Google Earth is part of the original territory occupied by the Beaver Indian First Nation, also known as the Dunne-za or the Tsattine, or "dwellers among the beaver"
