This view is one of Nims’ first in Cataract Canyon, which occurs downstream of the Confluence of the Green and Colorado River and extends to the end of Mille Crag Bend upstream from Narrow Canyon and the mouth of the Dirty Devil River. A dense stand of saltbushes and seepweed is present throughout the foreground and midground, and riparian vegetation along the right side of the view is a combination of mostly netleaf hackberry and a few desert olive.

A debris flow has crosses the view from a high-angle chute out of the view to the left, but the boulders deposited by this flood are apparent in the midground. This change exemplifies the foreground and midground of this view, where few desert shrubs have persisted the last 110 years. In contrast, most of the netleaf hackberry and at least one desert olive have persisted, showing that unlike other reaches of the Colorado River, the riparian zone is more stable than the desert vegetation.

Although one seepweed individual in the foreground clearly persists over the last 11 years, more turnover has occurred here, probably because of the severe drought that marked the first decade of the 21st century. Grizzlybear pricklypear cactus is now prominent, but this partially could be because shrubs that blocked the view of some patches in the 1999 view have died. Mormon tea individuals that have grown up in the debris-flow deposit look strikingly similar compared with the 1999 view. Biological soil crusts are prominent in the foreground and midground, in part because rainfall occurred shortly before this photograph was taken and the fact that the density of shrubs has decreased.
