The photographs in this collection are digital scans of slides put together as a slide show by A. Oscar Olson. Most of them were taken during a Glen Canyon river trip with SOCOTWA Expeditions in May, 1962; while the rest were taken on later visits to Lake Powell in the 1960s through 1990s. He took the later photographs in order to show the changes in the original locations brought about by the filling of Lake Powell reservoir behind Glen Canyon dam. The images depict the usual scenes of a SOCOTWA river trip, including the launch, days and events on the river, visits to attractions such as Hole In The Rock and Rainbow Bridge, camp scenes, and other events. All but a few of the images were made on 35mm Ektachrome film, which later faded to red. Mr. Olson asked Nelson Wadsworth, an archivist at Utah State University, to adjust the color digitally to return the images to their original color, which was largely successful. The images, however, were taken out of their original order during this process and thus are out of sequence. This is noted where applicable in the register. All photographs were taken in May, 1962, unless otherwise noted. All information for captions supplied by Oscar Olson on June 25, 2003.
