This is Devils Tower, it was very impressive. It was formed 60 million years ago when molten magma was forced into sedimentary rocks above it and then cooled underground. As it cooled it contracted and fractured into columns. Over millions of years the sedimentary rock eroded away and today Devils Tower rises 867 feet from its base and stands 1,267 feet above the river and 5,112 feet above sea level. The top of it is 1.5 acres and the diameter of its base is 1,000 feet.
People come from all over the world to climb it. It was our first National Monument, proclaimed by President Theodore Roosevelt in 1906.
Don't forget that you can click on the pictures to see them full-sized!
The light was at a bad angle on the picture of Larry and I but a man had kindly offered to take our picture. The view is lovely!
