Not long, from what i can see! Then again, you never know... A place i go often has a woods to the side and many, many beaver-cut trees are back there. I like this image, with the background so clear. The green accross the river is vivid and the water makes it seems somehow comforting (though i would not swim it, for how muddy it appears!) Take a look at my Beaver-cut tree. Not as good as your shot, as close as it is to the tree, but all the same. You might enjoy. :)

Crazy what those little dudes can do with just their teeth!

Isn't it amazing what those beavers can do with just their teeth? Whew! This is a unique capture and you have good detail. Thank you for posting :~)
