Summary
Album caption and index card: The camera station is too far forward and too far to the right for an exact match.The plants that densely occupy the higher ground of the old bar include saltcedar, seep willow, desert broom, catclaw, arrowweed, and some large western honey mesquites. The present exposed bar is probably low enough to be inundated by the regular daily high flows. Because of the slightly darker tones of western honey mesquite and catclaw foliage compared to the color of the riparian plants, the contact between the old high-water community and the new riparian community is apparent. Across the river where the talus slopes have a northerly aspect, the highwater community is mostly western honey mesquite and catclaw. This elongate [...]

Album caption and index card: The camera station is too far forward and too far to the right for an exact match.The plants that densely occupy the higher ground of the old bar include saltcedar, seep willow, desert broom, catclaw, arrowweed, and some large western honey mesquites. The present exposed bar is probably low enough to be inundated by the regular daily high flows. Because of the slightly darker tones of western honey mesquite and catclaw foliage compared to the color of the riparian plants, the contact between the old high-water community and the new riparian community is apparent. Across the river where the talus slopes have a northerly aspect, the highwater community is mostly western honey mesquite and catclaw. This elongate community appears slightly more open in 1974 (August) than in 1923 (September). The same highwater community below the camera station has a southerly aspect, and four species share dominance: western honey mesquite, wolfberry, creosote bush, and catclaw. On the slope in the foreground is Mohave Desert scrub vegetation comprised of ocotillo, brittlebush, creosote bush, Morman tea, and barrel cactus. Grand Canyon National Park. Coconino and Mohave Counties, Arizona. August 1974.
