When Stanton captured this view looking upstream from what is now known as the right scout point of Crystal Rapid, there was a considerable amount of sand among the boulders covered with dense biological soil crust. This high debris fan, probably an Early Holocene relict, was stable with a mature desert vegetation assemblage dominated by Mormon tea and perennial grasses.

A century later, the foreground shows the effects of trampling from river runners visiting the prominent scout point for Crystal Rapid. Most of the Mormon tea present in 1890 persist, although the biological soil crust and perennial grasses are victims of the foot traffic. Catclaw and goldenbush have either become established or are more clearly identifiable. The sandbars in the distance have deflated or at least are less obvious owing to the establishment of non-native tamarisk. The foreground surface has eroded – note the line on the foreground rocks where once they were buried – in response to the trampling.

Many of the Mormon tea persist, particularly the one in the right foreground, although the perennial grasses that once grew here have not reestablished and the biological soil crusts continue to be trampled. The tamarisk, which is leafed out and hence more visible than in 1990, appears to have grown somewhat.
