Stanton, who after all was planning a railroad, identified a large outcrop of Redwall Limestone, which he called the Marble Pier, as a place to secure a two-part railroad bridge across the mouth of 24.5 Mile Canyon. Nims stood atop this outcrop to secure this image showing the pool downstream from 24.5 Mile Rapid, a riffle, and 25-Mile Rapid in the distance. A large amount of eolian sand is present across the foreground. The shrubs on the slope are primarily Mormon tea, the river corridor is mostly devoid of vegetation, and a sandbar is prominent on the upstream side of the debris fan at 25-Mile Rapid.

After 106 years, the eolian sand has deflated to a moderate extent, and perennial vegetation has become established on its once mostly barren surface. Many of the same Mormon tea are still present, and a number of narrowleaf yucca are also visible. A few tamarisk are scattered along the shoreline. The sandbar upstream from 25-Mile Rapid has decreased in size

The tamarisk have increased greatly in both number and size in the intervening 15 years, creating a near-continuous line along the left side of the river. The amount of sand appears to be similar. Some of the yucca have died, but many of the Mormon tea still persist. The sandbar upstream from 25-Mile Rapid has increased, resembling its 1889 size.
