Nature Mystery Number 2!


I was out for a walk not too long ago and came across an awesome sight; evidence of a 6 foot tall beaver!!!!





Could this be a hold over from the last ice age which has been hiding out in the deep dark wood of Maine? After all during the last ice age there were beavers which measured about eight feet long and weighed close to 220 pounds.  What are the chances? Well, about as good as me seeing Bigfoot walking through the Oregon woods, not going to happen.

So, what is going on here?  Walk a few more feet further into the woods and you will find a beaver dam and the beginning of a beaver lodge. Since beavers can cut down trees as large as two feet around the beaver strolled by and thought hey this would make an excellent log for my beaver dam and got to chomping. Now while birch trees are a rather hard wood those amazing incisors they have easily make short work of this tree.  

Now the top set of chew marks is about 3-3 1/2 above the surface of the ground and the bottom cut is about 2 1/2 feet above the surface of the ground. Why is the top one so far off the ground?  It is a little hard to tell the how I took the picture, but there is a pretty significant hill on the left side of this picture. By looking a the wind blown shape of the tops of the surrounding trees it is obvious the wind blows over this area pretty strongly from the west (left side of the photograph.) As the wind blows across the hill the snow builds up deeper and deeper until the wandering beaver scopes out the tree for chopping.  As the winter nears an end the snow slowly starts to melt more of the base of the tree becomes uncovered and the beaver came back for another section of log. However, the beaver never had a chance to completely chip through the second section of tree before the snow melted out from underneath it.

Keep and eye out for mysteries in the forest around you!


Ps: If you have never seen just how into building dams beavers are take a look at the largest beaver dam anywhere in the world. Found in 2007, it is over 2,800 feet long!
