One of the most industrious critters we see in
the Boundary Waters is the beaver. I’m amazed at how quickly they can
build a dam. I’ve paddled into the wilderness where the was no beaver
dam, and then paddled out the same stream five days later to find a new
large one. We typically see beavers when they are swimming around camp.
This video, in contrast, shows rare footage of them walking around out of the
water and building a lodge.
