Our Beautiful Earth

So much of the beauty of our earth is hidden beneath the top layers of soil. One of the things I really enjoy when we travel in the western part of the United States, is looking at the areas which are cut when highways go through hills.

I found this photo tonight while looking at an article on Geology.com. I read several of the articles listed here each week. So much fascinating stuff to discover!!
