Standing on a Muav limestone promontory, Stanton took this view showing the head of 36-Mile Rapid. A debris fan on the lower right constricts the river, forming the rapid; a sandbar is clearly visible on the upslope side of the debris fan. Desert vegetation growing on the slopes includes Mormon tea, Utah agave, Anderson thornbush, and Engelmann hedgehog. Biological soil crusts are also present in the immediate foreground.

The boulders on the debris fan have been reworked or possibly have been covered by a small debris flow in the last century. Riparian vegetation has established on the debris fan and along the beaches. Some of the Mormon tea and Anderson thornbush have persisted the century. The number of Utah agave and Engelmann hedgehog have increased, and several new plants, including Apache plume, cottontop cactus, pricklypear, and turpentine bush, have become established. The amount of biological soil crust present has decreased slightly.

Engelmann pricklypear has greatly increased on the midground slopes in the past two decades, while many of the Utah agave, hedgehog, and cottontop cacti persist. A new sandbar, anchored by tamarisk, has been deposited on the riverward margin of the debris fan. The central part of the sandbar is dominated by longleaf brickellbush, and tamarisk is also common on the debris fan.
