As the Brown-Stanton Expedition continued downstream, Franklin Nims made another upstream view of Tilted Park. John Wesley Powell named Tilted Park for the prominent rotated Toreva blocks, the toes of which appear behind the cottonwood trees on river right. The view is across Rapid 10, which has no discernible waves at this high discharge of about 40,000 ft3/s. Desert vegetation appears on the rocky slope here.

In the foreground, eight individuals of Mormon tea persist while five have died. Individuals of other species, notably winterfat, have also persisted. Well-developed biological soil crusts appear in both the 1889 and 1992 views. Across on river right, tamarisk and coyote willow form a dense thicket with cottonwood trees appearing behind. Fremont cottonwoods have died on both sides of the river at Tilted Park. The camping beaches here appear to be larger, possibly because tamarisk has stabilized the banks on the right side of Rapid 10.

There has been little change in the intervening 18 years between photographs in the beaches, plants, and biological soil crusts, but major changes have occurred in the riparian thicket on river right across Rapid 10. The dead or dying non-native tamarisk trees now clearly can be distinguished from the coyote willow and other native species. Many of the individual plants that were present in 1992, including Mormon tea and winterfat, continue to persist, and the dense biological soil crusts distinguish the intershrub spaces.
