Death Valley National Park, California. Tubular orifices in the fine sediments at Salt Springs near the north side of Borax Camp allow discharge of water to the valley floor. Light areas are accumulations of salts from previous discharges. Circa 1960. Figure 10, U.S. Geological Survey Professional paper 494-B.

Album caption: General view of canyon wall near Camp Wylie. Red Kanab sandstone below and white Colob sandstone above. Utah.

Album caption: Kanab sandstone. Walls about 2000 feet. Zion Canyon. Utah. Index card: Canyon walls 2,000 feet high. Zion National Park.
thumbnail
Yosemite National Park, California. Silhouette view of the gorge that separates Liberty Cap from the Nevada Fall platform. This gorge was, at one time, the channel of the Merced River and still carries off some of the flood waters in spring. The trail to the top of the Nevada Fall is laid through it. Circa 1913.

Colorado National Monument, Colorado. Devils Kitchen, looking north from a ridge in the middle of No Thoroughfare Canyon. An erosional remnant of the Wingate Sandstone capped by the lowermost sandstone of the Kayenta Formation. Photograph by T.F. Giles, December 15, 1978. U.S. Geological Survey Bulletin 1508. Figure 57.

North Cascades National Park, Washington. Glaciers at the head of Luna Creek in Picket Range. This complex of ice patches illustrates the difficulty of counting and classifying individual glaciers. A glacier fed by ice avalanches ends in Luna Lake on the left. Avalanches from the large irregular hanging glacier that clings to the cliffs feed the debris-covered ice upslope from another lake (foreground, right center). A small ice patch fed by snow avalanches lies at the base of the cliffs in right center. September 27, 1960. Plate 3-D, U.S. Geological Survey Professional paper 705-A. 1971.

Gower Gulch at the north end of the Black Mountains. Borate-bearing fanglomerate partly sheared across steeply tilted borate beds. Basalt flow in playa clays in the distance. Mine portal at left of center. Death Valley National Park, California. 1938. Panorama in two parts. Photo 48 and 49. (see ttp00049)
thumbnail
Brecciated Ordovician (?) quartzite in basaltic fanglomerate at the north end of Artist Drive Hills near Mushroom Rock. Death Valley National Park, California. 1938.
thumbnail
Yosemite National Park, California. Yosemite Falls and surrounding cliffs, viewed from the valley floor. Only the head of Lower Yosemite Fall is visible through the trees. Dark zones of vegetation crossing the cliffs on the left reveal narrow terraces developed along zones of sheared rock. Sparseness of vegetation in the intermediate spaces is indicative of the absence of joints in the rock. Circa 1913.
thumbnail
Yosemite National Park, California. Bold exposure of unjointed Half Dome Granodiorite (in sun) capped by mostly well-jointed tonalite (in shade) making up Glacier Point. The contact between the two rock types angles upward to the left. Figure 38, U.S. Geological Survey Bulletin 1595.
thumbnail
Album caption: Flathead Co, Mont. Index card: Aerial view of Boundary Mountain-avalanche tracks visible. Glacier National Park. Flathead County, Montana. July 3, 1979.
thumbnail
Yosemite National Park, California. Three-quarters profile view of Royal Arches, showing the inclination of rock sheets and in-curving of partings under the edge of the rock terrace, a feature characteristic of exfoliation. Half Dome in the background. Circa 1913.
thumbnail
Yosemite National Park, California. Cascade Cliffs and Little Yosemite Valley. In few other places in the Yosemite region is the granite more continuously massive than in the Cascade Cliffs. Only one horizontal master joint divides the rock (in the lower left.) The scales on the cliffs are merely surficial features due to exfoliation. The dark streaks indicate the paths followed by the ribbon cascades which descend from the upland in the spring, when the snow is melting, and from which the cliffs take their name. In the background is Sugar Loaf (Bunnell Point). Circa 1914. Plate 45-A, U.S. Geological Survey Professional paper 160. Note: The Francois E. Matthes' papers and field notebooks are housed in the Brancroft...

Glacier Bay National Park and Preserve, Alaska. The iceberg projects 75 feet above the water. The nearer face, black with rock debris, was probably part of the base of the parent glacier. Harriman Expedition, 1899.
thumbnail
Sequoia National Park, California. Glacier polish, striae, and grooves above the head of Kern Canyon. The rock is aplite, which weathers more slowly than the coarser granite and, therefore, holds its glacial markings longer. Since being glaciated, the aplite has been somewhat disrupted into angular blocks by repeated frost action. Circa 1935. Figure 23, U.S. Geological Survey Professional paper 504-A.
thumbnail
Colorado National Monument, Colorado. Ladder Creek Monocline and Redlands Fault. View is northwest from a point near Little Park Road east of the monument. No Thoroughfare Canyon in the foreground, which is bordered on the left by northeastward-dipping beds of Wingate Sandstone at the northwest end of Ladder Creek Monocline. Old Serpents Trail, the lower part of which is barely visible, ascends this dipping block of rock. The dark Proterozoic rocks form the flat-topped bluff on the right and are exposed by the Redlands Fault which lies just above the sharply upturned remnants of the Wingate Sandstone. 1976. Figure 29, U.S. Geological Survey Bulletin 1508.
thumbnail
North Cascades National Park, Washington. Swirled banded gneiss made up of layers of dark and light-colored biotite quartz gneiss. The white rock, under the pick handle and in the upper left corner, is light-colored diorite. View is from the south ridge of Davis Peak. Circa 1967. Figure 5-A, U.S. Geological Survey Bulletin 1359.

Album caption and index card: Cliff outcrops of Cambrian and Ordovician rocks, viewed southward from Bighorn Pass, Gallatin Range. On right, lower cliff is Pilgrim Limestone; middle platy beds are Sage Limestone member of Snowy Range Formation; upper cliff is Bighorn Dolomite. Cliffs in cirque headwall (center left) are part of Indian Creek laccolith. Yellowstone National Park, Wyoming. Circa 1967. Published as Figure 7 in U.S. Geological Survey. Professional Paper 729-A. 1972. Note: Photos ret00205 and ret00206 form a panorama.
