February 6, 1991: Colorado River, Grand Canyon, River Mile 65.5, Palisades Creek, across canyon view from river left. Lava Canyon Rapid has changed considerably, owing to one or more debris flows over the past century from both sides of the river.

February 5, 1991: Colorado River, Grand Canyon, River Mile 52.8, Nankoweap, Downstream View from River Right. The river level is higher than it was in the original photograph, but the sand bars appear to have shifted and eroded; mesquite has increased, but not as much as the non-native tamarisk. Many of the Mormon tea plants visible in 1890 persist. Stake no.

February 5, 1991. Colorado River, Grand Canyon, River Mile 52.8, Nankoweap, Downstream View from River Right. The river level is higher than it was 1890, and overall the amount of sand lining the river has declined or is now covered with riparian vegetation. Some of the sand bars appear to have shifted and aggraded.

January 23, 1990: Colorado River, Grand Canyon, River Mile 61.4, Little Colorado River, Downstream View from River Right. A century later, many of the same plants are still visible, with some mortality and recruitment of the Mormon tea, catclaw, and pricklypear.

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.
