It is no secret that over time water will always win the battle over stone and actually just about anything for that matter! While on vacation on the coast of Maine I came across a great example of this, combined with one of my favorite things, antique granite.
Just south of Tenants Harbor is a great little beach that has tide pools, ledge out croppings and a relatively sandy beach. After awhile I noticed the culvert in the picture below. The entire length of it is made from locally quarried granite.
In the above photo you can pretty easily see the waterline. Smooth stones on the bottom and rough ones on top. I don't know when this was installed ,but water clearly already let its mark.
Water has no problem clearing a path!
