This downstream view is from a steep-angled talus cone on the left side of the Colorado River in Glen Canyon. This talus cone is covered by stabilized eolian sand, but rocks protrude through it. The high-water mark on the sandbar across the river is clear in this view; the vegetation stops abruptly and bare sand continues to the river. On the left side, sparse riparian vegetation occurs near water level, and the slope has individuals of Mormon tea and grasses.

Livestock trails crisscross the slope, and grazing appears to have decreased the number and coverage of perennial grasses. A new rill cuts into the slope in the center foreground; erosion on the slope may have increased as a result of the loss of cover. Across the river, the bare sand has mostly been eroded away and vegetation has established to the water on the point of the sandbar. In the left foreground, three Mormon tea plants persist from 1889. The prickly pear in the bottom left corner of the foreground is new, as are two Russian knapweeds downslope near the water. Another small but notable change is that the pointed rock at the center-left edge has broken off.

Even less sand is visible on the right bank, and riparian vegetation has become densely established to water level. In the foreground, three individuals of pricklypear and four of Mormon tea persist, as well as the two individuals of the non-native Russian knapweed in the center.
