A USGS repeat photograph that is a match to an E.C. LaRue USGS image from 1923, taken during the Birdseye Expedition, prior to Glen Canyon Dam. Note the increase in vegetation in this image. The 1923 image was taken along the Colorado River, at River Mile 197, from the left bank, and repeat images were taken by the USGS in 1972, 1983, 1994, and 2016.

This historic photograph shows a group of packhorses and several vehicles moving upstream on Salt Creek just upstream from Peekaboo Arch. Taken at the time that Canyonlands was established as a national park, it shows a wide channel with flanking narrow, high floodplains and colluvial terraces resulting from rockfall and eolian distribution under the bedrock walls.

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.
