X formations everywhere
There are several X's in the photo above but they are small and hard to see. This photo was taken in the area our children call "The X Forrest".
A Classic X Formation
The photo above is my personal favorite. I've seen fancier but none I like better than this one. It's made from peeled cedar poles. The branches have been twisted off and all the bark has been removed. This one is very old and has been there a long time but being made from cedar it will be there for a long time to come. This was found on a small creek that runs right thru the middle of the small town we grew up in.
This is the same formation but at a different angle. Notice how the creature weaved this all in place. It takes a smart critter to build something like this.
