Bog recon
The latest view of the beaver den on the farthest bog. I was about ten-fifteen feet away, standing on the old rail trail, which is shown in image 2, below. The beavers have managed to dam up their reservoir bog using the berm that makes up the rail trail. The rail trail itself is pock marked with puddles as a result of damage done by ATV machines.
In image 2, you can see where the beavers have reinforced the higher parts of the trail with their own damming (the reservoir is on the left in image 2).

The water level of the bog is now over two feet higher than the water on the rail trail. The trail is about two feet or more higher than the woodland on the right of the trail.
With the rail trail also existing as the local snow mobile trail, it will be interesting to see how the beavers cope with the noise and traffic that will occur this winter.
