Photo: Rainbow Arch, Lake Powell

This is another one of Stuart's photos.  Rainbow arch is at Lake Powell on the Arizona-Utah border.  It is not very accessible, and is reached best by boat.  People like to rent houseboats for vacations on Lake Powell, which was created by the Glen Canyon dam on the Colorado River not far north of the Grand Canyon.

This week we are showing photos of Vienna, Austria, on our Viva la Voyage travel photo site.
