Devil's Tower, National Monument
Rising some 1200 feet above the valley floor, the tower is visible for miles in any direction. The many columns on its side were formed over 60 million years ago, as molten magma forced its way into the overlying sedimentary rock and cooled underground.
Thank you Brenda for the beautiful card!
