The Castle Rock in Boulder Canyon. The canyon is about 17 miles in length, cutting deep down through the metamorphic rocks of the foothills, so that in some places the sides of the canyon rise up nearly 3,000 feet above its bed. Boulder County, Colorado. 1873.

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.

Album caption: Devils Gate Bridge. The most attractive feature of the canyon is the roar of the waters of the Weber as they roll over the immense masses of rock in its bed, with the rush and tumult of a mountain torrent. For 4 miles we are enclosed with nearly perpendicular walls of gneiss, 2,000 feet in height, forming the central portion of the Wasatch Mountains; the river rushing through it at right angles. The rocks are beautifully banded everywhere. There are also coarse aggregations of quartz and feldspar all along the sides of this channel; and high up on the steep mountain flanks are vast deposits of boulders and fine sand. Weber County, Utah. 1869. Handwritten notes on album caption: None Index card:...

Colorado National Monument, Colorado. Fruita Canyon, looking northeast from a point on Rim Rock Drive above the head of the canyon. Dark Proterozoic rocks floor the canyon, above which are the slopes of the red Chinle Formation and the cliffs of Wingate Sandstone capped by the lower resistant beds of the Kayenta Formation. Beyond the Grand Valley are the dark Book Cliffs and the more distant, light-colored Roan Cliffs. May 28, 1970. Figure 45, U.S. Geological Survey Bulletin 1508.

Death Valley National Park, California. West flank of the Black Mountains north of peak 4214, just south of Sheep Canyon in the lower right. The skyline ridge dropping to Death Valley, left and center, is the approximate profile of the surface of the Copper Canyon turtle back and is underlain near the crest by broadly arched metasedimentary rocks that grade into metadiorite near Sheep Canyon. 1957. Figure 3, U.S. Geological Survey Professional paper 413.

Panoramic view (slight break between Nos. 102 and 103), looking north down Sheep Creek Canyon from top of old fan. Shows especially old conglomerate (Pleistocene?) now deeply dissected. White beds in foreground are gypsiferous, probably Tertiary. Mass on far side of canyon at right is probably mostly granite. In right distance of No. 102, just beyond vertical white mass, are rocks shown in No. 99. Northwest part of T. 17 N., R. 6 E., 22 miles northwest of Silver Lake, Crucero Quadrangle. San Bernardino County, California. October 16, 1917.

Sequoia National Park, California. West across the canyon of Marble Fork Kaweah River, showing one of the great cliffs of white marble from which the stream takes its name. The cliff is cut from a vertical bed of marble transected by the canyon. To the left of the marble bed are thin beds of various dark-hued metamorphic rocks. All of these strata are the stubs of a huge fold that probably once rose to a height of several thousand feet, but whether the upper portion of the fold (anticline) lay to the right or left is unknown. Circa 1935.
