Album caption and index card: This view, taken in March, shows a greatly diminished flood-line community, but this reduction in plant biomass is more apparent than real-the shrubs comprising the community are leafless at this season, whereas in the 1923 photograph, taken in September, the plants were in full leaf. The streamside plants that were present in 1923 and which persist to the present are willows. Unlike the condition in 1923, the beach at Granite Park now supports a dense growth of plants. The dominant species on the beach are willow, arrowweed, saltcedar, camelthorn, red brome, and Bermuda grass. All but the first two species have been introduced to this continent from other parts of the world. Feral...

Album caption and index card: This upstream view was taken from a point just above Spring Canyon, 328.9 kilometers below Lees Ferry. The Middle Cambrian Bright Angel Shale, mostly covered by slope wash, is at river level. A well-developed community occurs above the flood line on both sides of the river. At the present river stage, a large bar, unoccupied by plants, is exposed. (Altitude 454 meters). Coconino and Mohave Counties, Arizona. 1923. (Photo no. 633 by E.C. LaRue). Portion published as Figure 61A in U.S. Geological Survey. Professional Paper 1132. 1980.

Album caption and index card: The old camera station lies beneath Lake Mead silt several meters below and to the right of the new position. Before Hoover Dam was built the thalweg altitude was roughly 275 meters; now the thalweg altitude exceeds 350.5 meters, representing an accumulation of 76.2 meters of sediment. Saltcedar is the only plant seen on the deeply cracked silt deposit. Many of the plants are dead in this August view, presumably from submergence during earlier months when this site was covered by water to a depth of 2.7 to 3.7 meters. Some taller plants survived. Seedlings growing from the deep cracks in the foreground became established after the water receded. This scene illustates the dynamic nature...

Album caption and index card: This upstream view was taken from a point 168 meters above the Colorado River and shows Granite Park, 336 kolometers below Lees Ferry. A flood-line community is strongly developed along this section of the canyon. Some trees have become established at the edge of the river, a habitat that is here more stable than usual because of the great width of the valley floor. (Altitude 442 meters). Grand Canyon National Park. Mohave County, Arizona. September 28, 1923. (Photo no. 642 by E.C. LaRue). Portion published as Figure 64A in U.S. Geological Survey. Professional Paper 1132. 1980.

Album caption and index card: The Lower Marble Canyon ends at about kilometer 414.3 and the steep walls of the Inner Gorge give way to less steep talus slopes. In this veiw, looking down the canyon of the Colorado River 437.6 kilometers below Lees Ferry, the flood-line community is well developed above the conspicuous highwater line. The Middle Cambrian Bright Angel Shale is at river level. Typical Mohave Desertscrub species of the foreground include ocotillo, white bursage, and agave. The flood-line community includes western honey mesquite and catclaw. (Altitude 282 meters). Grand Canyon National Park. Mohave County, Arizona. October 13, 1923. (Photo no. 747 by E.C. LaRue). Portion published as Figure 72A in...

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...

Album caption: The new flood line now lies below the large rock and several plants of brittlebush grow on the slope between the new and old flood lines. The bar in the foreground is unusual in that no plants have become established there. The Inner Gorge is narrow here and during times of high flow the bar is flooded, making for an unstable surface for plant establishment. Men in raft by sand bar for scale. Grand Canyon National Park. Mohave County, Arizona. August 26, 1972. No index card. Published as Figure 70B in U.S. Geological Survey. Professional Paper 1132. 1980.

Album caption and index card: This photograph was taken from the small promontory of rocks seen beyond the fan in photo nos. 83 and 84, and shows in close view the same large tree near the river as seen in the previous views. For the tree to have reached this size would probably require 10 more more years of growth. Thus, the tree became established in about 1892 or earlier and persisted until at least 1923. (Altitude 408 meters). Grand Canyon National Park. Mohave County, Arizona. 1902. (Photo no. 911 by N.H. Darton). Published as Figure 68A in U.S. Geological Survey. Professional Paper 1132. 1980.

Album caption and index card: View down the V-shaped canyon cut through Precambrian metamorphic rocks. The stratified formation capping the Precambrian rocks is the Lower and Middle Cambrian Tapeats Sandstone. The far skyline is defined by a formation of the Pennsylvanian and Permian Supai Group. The sand deposit in the foreground and the one across the river are both at the mouths of minor tributary canyons 360.7 kilometers below Lees Ferry. A flood line is apparent from stains on the rocks of the opposite shore and no plants are visible below that level. (Altitude 408 meters). Grand Canyon National Park. Mohave County, Arizona. October 2, 1923. (Photo no. 665 by E.C. LaRue). Portion published as Figure 67A in...

Album caption and index card: A dense community of saltcedar, arrowweed, and seep willow has become established along the shore on both sides of the Colorado River. The fan on the right is more heavily overgrown by plants than before, except for the formerly stabilized high terrace which now seems to be covered by a sand deposit. The large tree on the opposite bank in photo no. 87 has not persisted to the present. The Colorado River no longer floods the large bare area with boats and people on it; as a result, fine material, deposited by flooding on Diamond Creek, now covers the gravels that were present earlier. Bermuda grass grows in moist soil near the shelters. The lower reach of Diamond Creek (foreground) is...

Album caption and index card: This upstream view of the Colorado River was taken from a hill above the mouth of Maxson or Reference Point Canyon, 406.0 kilometers below Lees Ferry. At the time of the photograph, barren silt accumulations deposited during floods could be seen high on the steep walls of the Inner Gorge. Dashed line on published photo shows location of silt bank visible in photo no. 92, taken after completion of the Hoover Dam. (Altitude 322 meters). Grand Canyon National Park. Mohave County, Arizona. October 136, 1923. (Photo no. 747 by E.C. LaRue). Portion published as Figure 71A in U.S. Geological Survey. Professional Paper 1132. 1980.

Album caption and index card: This photograph was taken form the left bank 313.6 kilometers below Lees Ferry. A Quaternary basalt flow is seen at river level on the right. The canyon of the Colorado River is broad enough here so that the scouring action of flood waters is dampened and some perennial plants became established in the alluvium near the river. A flood, 6 days earlier, overtook the U.S. Geological Survey crew at Lava Falls, 25.1 kilometers upstream from here and the river stage increased by 6.7 meters. The signs of recent wave action high on the beach in this photograph probably stem from the same flood. Several plants such as the tree (Fremont cottonwood or willow) at right midground, desert broom (left...

Album caption and index card: Because the old camera station is now overgrown by saltcedar and desert broom, this photograph was taken from a slightly different location than in 1923. The tree at left is Goodding willow and is the same plant as in the earlier view (photo no. 73). Bermuda grass now grows on the beach near the tree. The flood-line community at the mouth of Two Hundred and Ninemile Canyon comprises western honey mesquite and catclaw. Although not evident in the photograph, close field inspecdtion revealed that both species, trimmed through grazing by burros, are infested by mistletoe. Grand Canyon National Park. Mohave County, Arizona. 1974. Appears as Figure 62A (photographs transposed in publication)...

Album caption and index card: Diamond Creek enters the Colorado River 363.2 kilometers below Lees Ferry and is the first place in that distance where vehicles can reach the river. The mouth of Diamond Creek was visited by Ives and his party in 1858 and was the terminus of the Wheeler Expedition in 1871. The Diamond Creek Hotel was in operation here for sightseers from 1884 to 1889 before scenic areas farther east were developed. In this upstream view, the only plant at the river's edge is a large tree visible on the opposite bank in a protected area below a bar. Large plants on the fan at the mouth of Diamond Creek (right midground) are probably mesquites. On the uppermost sandy terrace of the fan a dense growth...

Album caption and index card: The U.S. Geological Survey team has moored its boats near a large rock at a sand bar on the right bank, 368.0 kilometers below Lees Ferry. Although no flood-line community is found on the steep walls of the Lower Granite Gorge, the flood line is visible because of stains on the rocks of the talus slopes. No plants are found below that line, and above it are seen widely scattered desert shrubs. (Altitude 395 meters). Grand Canyon National Park. Mohave County, Arizona. October 7, 1923. (Photo no. 690 by E.C. LaRue). Portion published as Figure 70A in U.S. Geological Survey. Professional Paper 1132. 1980.

Album caption and index card: The boulder with the man standing on it in the photo no. 83 is now hidden by saltcedars, which form a discontinuous strip along both shores. The depth of sand around the base of the boulders is less now than before. The sand deposit is now partially stabilized by dropseed (the coarse grass), red brome, and Russian thistle. Signs of burro are abundant. Grand Canyon National Park. Mohave County, Arizona. September 29, 1976. Published as Figure 67-B in U.S. Geological Survey. Professional Paper 1132. 1980.

Album caption and index card: The clump of large shrubs seen near the boats in photo no. 75 are gone and have been replaced by a few small Goodding willow which are obscured by the more abundant saltcedar. The band of arrowwed has expanded and now occupies, with desert broom, the sandy beach between the saltcedar fringe along the river and the scarp below the first terrace. On the terrace, the dark shrubs of the old flood-line community are mainly western honey mesquite with some catclaw. Grand Canyon National Park. Mohave County, Arizona. 1974. Published as Figure 63B in U.S. Geological Survey. Professional Paper 1132. 1980.

Album caption and index card: Saltcedar, arrowweed, and seep willow grow thickly at the site occupied earlier by the single tree (see photo no. 85). Slightly to the right of that position can be seen a clump of cattails. Grand Canyon National Park. Mohave County, Arizona. August 25, 1972.

Album caption and index card: Silt had accumulated to a depth of over 50 meters in this reach of the Lower Granite Gorge by 1948, approximately 13 years after the completion of Hoover Dam. The old camera station is now within the reservoir area of Hoover Dam and is buried beneath Lake Mead silt. The new station has been moved upslope. Saltcedar is the dominant plant of the foreground. The dashed line in photo no. 91 marks the approximate location of the surface of the silt deposit seen in this view. The vertical silt bank extends approximately 5.5 meters above the present water surface and has developed since 1963 when the water level in Lake Mead was lowered sharply at the time of impoundment of water in Lake Powell...

Album caption and index card: What appear to be catclaw and western honey mesquite form a dense community lining the channel of Cave Canyon which enters the Grand Canyon from the left bank 441.3 kilometers below Lees Ferry. This community merges with the flood-line community of the Colorado River valley. There is apparently a moist area in a travertine deposit on the bank opposite the mouth of Cave Canyon which supports a low growth of plants that extends to the edge of the river. The slopes near the camera station are dominated by creosote bush and white bursage. (Altitude 280 meters). Grand Canyon National Park. Mohave County, Arizona. October 15, 1923. (Photo no. 761 by E.C. LaRue). Portion published as Figure...
