Album caption and index card: This downstream view was taken at kilometer 350.3 from a station just below the mouth of Two Hundred and Seventeenmile Canyon and only a short distance into the Lower Granite Gorge. Except where sediment has entered the canyon from tributaries, there are few sand or gravel shores within the Lower Granite Gorge, so steeply have the Precambrian rocks eroded to river level. Even where substrate exists for riparian communities, as on the foreground debris fan, the narrowly defined valley tends to increase the depth of flood waters making these habitats too unstable for plant establishment. The flood-line community is also missing on the steep slopes above the river. (Altitude 414 meters)....

Album caption and index card: The camera station is now in a dense stand of arrowweed. Many saltcedar plants grow around the edge of the gravel bar where a half century earlier only one plant was visible. In addition, two western honey mesquites, desert broom, Goodding willow, and desert isocoma grow near the shore. The flood-line community, mainly of catclaw with a few western honey mesquites, is still present but seems diminished. Close inspection of this community shows that there are numerous burro trails, and the basal portions of flood-line community shrubs are stripped of foliage where in reach of animals. Grand Canyon National Park. Mohave County, Arizona. August 25, 1972. Published as Figure 66-B in U.S....
