Repeat photography of 128-Mile Rapid on the Colorado River, Grand Canyon, AZ

A repeat photographic series of 128-Mile Rapid on the Colorado River, Grand Canyon, AZ, looking upstream from the top of a schist outcrop just below 128-Mile Rapid from a point on the left bank, 66.8 miles below the Little Colorado River and ½ mile below Specter Chasm, at RM 128.4. Note changes in the debris fan that reduced the constriction of the rapid. The original 1923 photograph was taken by E.C. LaRue during the 1923 USGS Birdseye Expedition, and has a panoramic view, whereas the later image taken by Dr. Teo Melis, USGS in 1991, is at a different scale and provides a partial match.
