On Lake Powell Utah.
Glen Canyon is an mind-bogglingly vast canyon in deep red rock country, which has been filled with North America's largest man made lake, Lake Powell. Surrounded by nothing but red slick rock, the crystal blue lake is strikingly out of place and looks like it belongs on Mars. Lake Powell would be totally deserted were it not for its popularity with house-boat owners, who sail around this dead and beautiful expanse. Original public domain image from Flickr
