From Life, Comes Life
This is only really about 10 inches high. But as I was walking down a trail I heard it and could not help but go over and take a look.
The water in this case flowed down across parts of the trail and at a flat section it had somehow managed to find its way to some logs and follow and slowly eat out parts of the log to create this little flow.
I find it interesting that from the life of the tree comes the giving life of water. That now supports the mosses and small vegetation that are growing on the nursing log.
