Abstract Ray Turner aims his camera with great care at a precise spot on a nearby ridge at Saguaro National Park, east of Tucson, Arizona. First, Turner makes sure that two large saguaros—one with four armlike branches reaching out and up, candelabra-style, and the other just a column with no branches yet—are aligned with the same Santa Catalina mountain peaks in the background in exactly the same position as in previous pictures. Then, carefully, Turner checks his position and camera direction with his compass and global positioning system. Finally, he snaps several pictures of the saguaros and their surroundings, just as he has done periodically since 1962.
