This downstream view shows the bottomland on the left side of the Colorado River and the riparian vegetation that mantles both banks. On the near (left) bank, the species present are the usual ones, including desert olive, Goodding willow, netleaf hackberry, and coyote willow. The desert vegetation includes Mormon tea and other species on the rocky slopes to the left and saltbushes on the finer-grained bottomlands to the right. The finer-grained soils sustain biological soil crusts, which are apparent at right center. The front barrel of the transit that Stanton used to survey this part of his railroad route is visible on the left side, and one of the surveyor helpers is seated in the center of the view but is hard to discern in the grainy image.

A small debris-flow deposit now mantles the cone of soil extending from the left side of the view, likely originating from the local cliffs of Honaker Trail Formation. The extent of deposition is apparent from the exposure on rocks to the left and the residual extent of biological soil crusts on the right. Rockfall have added new boulders to the view, notably in the midground. These changes, while affecting the immediate foreground and the camera station, did not cause significant changes to most of the view, where persistent rocks are surrounded with several persistent shrubs, including Mormon tea to the left and four-wing saltbush to the right.

Yet another rockfall has occurred in the midground to the left, and the new rocks appear fresh and white compared with those that have been laying on the surface of the bottomland since at least 1889. Many shrubs have died, probably during the severe drought that prevailed over most of the intervening 17 years, but many individuals in the midground persist, including four-wing saltbush, Mormon tea, and shadscale. Biological soil crusts are prominent, in part because fewer shrubs are in the foreground and recent rainfall.
