Album caption: Newly fallen boulder from Mt. Jackson, plus swath at cut through trees. Montana earthquake area. August 1959. Index card unavailable.

Album caption and index card: Mud volcano near Pocket Basin in the Lower Geyser Basin. The mud is formed by chemical decomposition of the rocks chiefly by the action ofr carbon dioxide and sulfuric acid. The splatter, 5-6 feet high, is caused by the escaping gases. Yellowstone National Park, Wyoming. 1970. Published as Figure 53 in U.S. Geological Survey. Bulletin 1347. 1971.

Upstream or east part of slide showing trough prepared on spillway. Faster moving part of slide debris in foreground, slower part in middle distance. Note trees lined in direction of motion from right background to left foreground. Montana earthquake area. Madison County, Montana. August 1959. (Aerial view). No index card. Note: Similar to sjr00210.

Bank slump of thick colluvium, west shore of Hebgen Lake, about a half mile south of dam. Montana earthquake area. Gallatin County, Montana. August 1959. (Aerial view). No index card. Note: Similar to sjr00251.

Album caption and index card: Skyline of the Gallatin Range in northwestern Yellowstone National Park, as viewed from a point on the road between Canyon Village and Norris Junction. The range consists chiefly of Paleozoic and Mesozoic sedimentary rocks and Precambrian metamorphic rocks that were uplifted by folding and faulting of the earth's crust. The dark-gray rocks along the roadcut in the left foreground are rhyolite lava flows of the Solfatara Plateau. Yellowstone National Park, Wyoming. 1970. Published as Figure 3 in U.S. Geological Survey. Bulletin 1347. 1971.

Album caption and index card: Rocks along the Lamar River banks are coarsely banded Precambrian gneisses more than 2.5 billion years old, some of the oldest rocks in Yellowstone National Park. View shows coarse banding and texture of the gneiss; minerals include quartz, feldspar, and biotite (black mica). Yellowstone National Park, Wyoming. 1970.

Album caption and index card: Brecciated rhyolite lava flows along the Firehole Canyon drive. As a lava flow moves outward from its center of eruption, a chilled crust develops along its upper surface and outer edges because of the cooler temperatures in those parts of the flow. Continued movement of the still-molten rock in the interior of the flow causes this crust to break up (brecciate) into angular blocks. The blocks are then tumbled along until the whole mass finally solidifies. Yellowstone National Park, Wyoming. 1970. Published as Figure 31 in U.S. Geological Survey. Bulletin 1347. 1971.

Album caption: None provided. Index card: The Madison slide; Earthquake Lake is in the background. The white ridge of dolomite boulders which formed the leading edge of the slide is on the left and the main mass of the slide shows in the right center of the photograph. In the lower left corner of the photograph are the parallel rows of pine trees which once flanked the Madison River. Part of former U.S. Highway 287 still shows beyond trees. Montana earthquake area. Madison County, Montana. August 1959.
