The Stanton expedition had trouble passing through the Roaring Twenties, a reach of closely spaced rapids between mile 20 and 27. With the drowning deaths of the previous summer on their minds, the crew lined and portaged most of the rapids in this reach. While a lining was underway around the rapid at mile 23.3, Robert Brewster Stanton made this upstream view at 11:30 AM. Apache plume, a facultative riparian species, forms the old high-water zone on the right side.

Apache plume has decreased in more original and matched Nims-Stanton views than it has remained the same or increased. It has decreased in this view for two reasons: a debris flow from the unnamed canyon at right has destroyed many plants in the right foreground, and operation of Glen Canyon has reduced the amount of water available for those plants in the center. In addition to persistent individuals of Apache plume, three individuals of Mormon tea and three of Anderson thornbush around the rock at right center have persisted over the last century. The sand bar at left center has increased in size; sand bars in this reach typically have decreased in size over the last century because of erosion during high, clear-water releases from Glen Canyon Dam.

A small debris flow has deposited several new boulders in the foreground since 1990, probably during a spate of debris flows in this reach in 1993-1994. Many of the plants present in 1990 in the foreground were destroyed by the debris flows, although some, including a cluster of longleaf brickellbush at center, remain. Several new shrubs have become established and the tamarisks on the opposite bank have become much denser. The once prominent line of Apache plume has decayed into scattered individual plants to limit intraspecific competition for water.
