A USGS repeat photograph of Glen Canyon Dam taken on April 20, 2011 as a match to the 1889 Franklin Nims image of the site before the dam was built, at Colorado River mile -14.7, during the Stanton Expedition. This view was also matched in 1992 by the USGS. The view is taken upstream from river left.
