Album caption: Stereoscopic pair showing Albertella from lower member of the Silver Hill Formation, north rim of cirque east of Black Lion Mountain, at 9,600 ft elevation. Published as figure 6D.
thumbnail
Album caption: Rock pinnacles of deeply weathered piles of teetering rock, interpreted as not to have been covered by the icefield glaciation, rising 10 to 20 m above the smooth glaciated surface. Divide is above rock basin south of Tendoy Lake, looking south. Published as figure 19A.
thumbnail
Album caption: View northeast from same spot as figure 19A, with Granite Mountain in background. In contrast to the pinnacles, the smooth surface of most the divide area has been glacially polished. Published as figure 19B.

Album caption: Metamorphic mineral assemblages of slightly calcic pelitic rocks in and around the Taconic allochton. Photomicrographs of triply zone plagioclase from (A) saple 3-3 (cross-polarized light). Southwestern Massachusetts and adjacent Connecticut and New York. ca. 1966. Published as figure 9-A in U.S. Geological Survey. Professional paper 1113. 1981.

Album caption: Devonian Jefferson Dolostone thrust upon the Mississippian Lodgepole Limestone. Location is west slope of 8,938-foot peak west of Lion Mountain. The Jefferson is highly brecciated and yellow, typical of that below the main thrust of Proterozoic quartzite at head of Gold Creek; its presence here suggests that this thrust of extended this far east. Man’s hand is parallel to bedding in the Lodgepole. Published as figure 24.

Album caption: Chert in lower member of the Phosphoria Formation, cliffs in sec. 10, T. 2 S., R. 10 W., east of Devils Hole north of Canyon Creek. Note lamination in dolostone, caused by quartz sand in crossbeds, that passes as a ghost lamination into the chert. Published as figure 12.

Album caption: Metamorphic mineral assemblages of slightly calcic pelitic rocks in and around the Taconic allochton. Photomicrographs showing (B) late plagioclase including folded foliation defined by dust trains; the sigmoidal fold is in a single crystal, sample 340-1 (plane-polarized light). Southwestern Massachusetts and adjacent Connecticut and New York. ca. 1966. Published as figure 11-B in U.S. Geological Survey. Professional paper 1113. 1981.

Album caption: Contact between Kootenai Formation and Colorado Group, on north side of Trapper Creek, south slope of 6,484-foot peak. Visible relief is about 500 ft9150m) [sic]. Top of the Kootenai is a gray gastropod limestone, succeeded by a massive (5--10 m) greywacke bed of the Colorado. Contact is just above right-hand talus slide marked by arrow. Published as figure 14A.

Abum caption: Glendale, Montana in 1983. Bedrock geology of the Vipond Park 15-minute, Stine Mountain 7 1/2-minute, and Maurice Mountain 7 1/2-minute quadrangles, Pioneer Mountains, Beaverhead County, Montana.

Abum caption: Glendale, Montana, in 1883. This old drawing of Glendale, viewed from the southeast, shows the town in more thriving days. Center of activity then was the smelter (left center) that processed the ore material mined at Hecla and vicinity. Only the chimney, a few shells, and cellar holes of buildings remain in the town. Trapper Creek valley extends from upper left to lower right in the perspective. The foreground is underlain by Cretaceous sedimentary rocks of the Colorado Group. The hills in the upper right part of the picture are south of Dry Hollow Gulch; from left to right the peaks against the skyline are at 6,500 ft, 6,700 ft, and 6,628 ft elevation on the Vipond Park topographic quadrangle...
