Pakwaw Lake Beaver Community 1945 2
This 1945 aerial photo does not show any clear and abundant beaver activity. Beavers appear to be present in some of the small open wetland areas marked with an aterix (*), but nothing compared to the 2007 density.
Note the location of the highway on the old Glacial Lake Agassiz beach line (marked with >>>>>), which shows a very light treeless ridge on the black and white aerial photo.
