Repeat photography images 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 since 1923 that reduced the constriction of the rapid.

January 18, 1890: Colorado River, Grand Canyon, River Mile 52.8, Nankoweap Creek, Downstream View from River Right. Uncharacteristically, Stanton changed lenses and took two similar views from the same location looking the same direction. This view was taken with what is known as a normal lens, as opposed to the previous view, taken with a wide-angle lens.
