Indiana Dunes National Lakeshore, Indiana. Storms with high winds and waves create steep narrow beaches, like this one where winter storms are frequent and especially destructive. Page 28 (bottom left), U.S. Geological Survey Circular 1085.

View toward the Carnegie Institution Marine Biological Laboratory aquarium and wharf, showing the amount of retreat of the beach line during the October 1910 storm. The line formerly extended seaward on the piles that support the aquarium. Dry Tortugas National Park, Florida. June 1911.

Glacier National Park, Montana. Northwest at the upper end of Red Eagle Valley, 2 miles southeast of Red Eagle Glacier. Trail in the center. Almost-a-Dog Mountain in the rear. July 1914.

Yosemite National Park, California. Glaciated rock between Mono Pass and Parker Pass. The direction of ice motion was from the foreground on the right toward the distance on the left. An angular cavity, due to the plucking of a block separated by joint planes, was modified by subsequent abrasion. The hill beyond is a spur of Mount Gibbs. 1903.

Yosemite National Park, California. Glaciated rocks between Mono Pass and Parker Pass in the Sierra Nevada. The direction of ice motion was from right to left. A joint face on the lee side, exposed by the plucking away of a block, remains unscored. 1903.
thumbnail
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)

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.

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.
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.

Yosemite National Park, California. Glaciated floor and side of upper Merced Canyon. All the rock features shown are smoothed and polished by the ice. In few places in the world is glacier polish more abundant than here. The row of stones in the foreground serves to mark the trail across the otherwise featureless rock floor. Circa 1914. Plate 36, U.S. Geological Survey Professional paper 160.
