I spent 24 hours at the Grand Canyon and took many many pictures.  This one is looking east from Hopi Point as the sun sets. By now there are tripods all along the railing all of us trying to determine the best place for sunset.  By the time sunset arrived the tripods overlapped each other and it was hard to find an open space at the railing.

The shadows shifted every minute so it was hard later to choose the best composition.  I liked this one as there is still sky and the light and shadows are so pronounced.
