The Hammerhead is at the center of this picture taken from the Royal Arch. Behind the Hammerhead is the Third Flatiron and, further back, the top of the First Flatiron can be seen. Left of the Third is the eastern Ironing Board. In the lower left corner is Tangen Tower, and, to its right, the first slab of the Fourth Flatiron. Boulder, Colorado, May 2007.
