Album caption and index card: Augen gneiss of the basement complex. Coarse augen gneiss in the bed of Raven Fork below Breakneck Ridge. Knife, 3.3 inches long, lies on metasandstone inclusion; other fine-grained layers are mylonitic. Great Smoky Mountains National Park. Ravensford quadrangle, Swain County, North Carolina. ca. 1950. Published as Figure 3-A in U.S. Geological Survey. Professional Paper 349-B. 1963.
Album caption: Photomicrograph of metadiorite, north slope of Clingmans Dome. Finer grained metadiorite showing micrographic quartz and oligoclase interstitial to zoned plagioclase, all penetrated by hornblende. The opaque areas are magnetite. Crossed nicols. Great Smoky Mountains National Park. Swain County, North Carolina. ca. 1950. No index card. Published as Figure 27-A in U.S. Geological Survey. Professional Paper 349-B. 1963.
Album caption and index card: Metasedimentary inclusions in augen gneiss of the basement complex. Metasandstone in gneiss of the Ravensford body, north end of Big Cove. Southwestward-facing joint showing tongues of augen gneiss and isolated porphyroblasts of feldspar in metasandstone. The lower part of the ledge is typical of the coarser northern phase of the Ravensford body. Eastern Great Smoky Mountains, Ravensford quadrangle, Swain County, North Carolina. ca. 1950. Published as Figure 4-A in U.S. Geological Survey. Professional Paper 349-B. 1963.
Album caption and index card: Folds in Great Smoky Group. Second generation folds in metasandstone and schist, showing absence of axial-plane foliation and parting along folded schistosity. U.S. Highway 19 near Wilmot. Eastern Great Smoky Mountains, Swain County, North Carolina. ca. 1950. Published as Figure 34-A in U.S. Geological Survey. Professional Paper 349-B. 1963.
Album caption and index card: Gneissic metasandstone and schist showing extreme metamorphic reconstitution in the Ocoee series. The more argillaceious beds consist of segregation lenses of biotite schist and of quartz-feldspar rock similar in composition to the lighter colored metasandstone beds. Small lenses and pods of pegmatite have formed in both types of rock. Roadside quarry on southwest flank of Ela dome. Eastern Great Smoky Mountains. Swain County, North Carolina. ca. 1950. Published as Figure 43 in U.S. Geological Survey. Professional Paper 349-B. 1963.
Album caption and index card: Metasedimentary inclusions in augen gneiss of the basement complex. Folded metasedimentary layers and pegmatite in augen gneiss, U.S. Highway 19, 3 miles west of Soco Gap. Eastern Great Smoky Mountains, Swain County, North Carolina. ca. 1950. Published as Figure 4-B in U.S. Geological Survey. Professional Paper 349-B. 1963.
Album caption and index card: Flattened quartz pebbles in Great Smoky Group. Quartz-feldspar conglomerate of the Thunderhead sandstone showing severely flattened quartz pebbles and relatively undeformed microcline. Becks Bald, three quarters of a mile southesast of the summit. Great Smoky Mountains National Park. Swain County, North Carolina. ca. 1950. Published as Figure 34-B in U.S. Geological Survey. Professional Paper 349-B.
Album caption: Photomicrograph of metadiorite, north slope of Clingmans Dome. Coarser metadiorite showing plagioclase penetrated by amphibole, which contrains ghhosts of former pyroxene (darker areas) originally bounded by plagioclase. Great Smoky Mountains National Park. Swain County, North Carolina. ca. 1950. No index card. Published as Figure 27-B in U.S. Geological Survey. Professional Paper 349-B. 1963.
Album caption and index card: Calc-Silicate Granofels ("Pseudodiorite"). Stream pebbles of varied granofels in Thunderhead sandstone. Scale in inches. Eastern Great Smoky Mountains, Swain County, North Carolina. ca. 1950. Published as Figure 42-A in U.S. Geological Survey. Professional Paper 349-A. 1963.
Album caption and index card: Calc-Silicate Granofels ("Pseudodiorite"). Gray biotitic metasandstone converted to patches of white quartz-plagioclase granofels with prominent hornblende porphyroblasts. Thunderhead sandstone in Bradley Fork, 2.8 miles above Smokemont Campground. Great Smoky Mountains National Park. Swain County, North Carolina. ca. 1950. Published as Figure 42-B in U.S. Geological Survey. Professional Paper 349-B. 1963.
Album caption: Calc-Silicate Granofels ("Pseudodiorite"). Photomicrograph showing sievelike porphyroblasts of hornblends and garnet with fine grained quartz and clinoqoisite. Granofels in Thunderhead sandstone, Richland Mountain, 4 miles east of Newfound Gap. Great Smoky Mountains National Park. Swain County, North Carolina. ca. 1950. No index card. Published as Figure 42-D in U.S. Geological Survey. Professional Paper 349-b. 1963.
Album caption and index card: Calc-Silicate Granofels ("Pseudodiorite"). Biotite-garnet-quartz-plagioclase granofels (lighter colored patches) in Roaring Fork sandstone, northwest of road 2 miles south-southwest of Big Witch Gap. Eastern Great Smoky Mountains, Swain County, North Carolina. ca. 1950. Published as Figure 42-C in U.S. Geological Survey. Professional Paper 349-B. 1963.
Album caption and index card: Photomicrograph of medium-grained felspathic sandstone, Thunderhead sandstone. Largest subangular grains are quartz; smaller cloudy grains are sericitic feldspar; small opaque grains are metamorphic biotite. Plane plane. Eastern Great Smoky Mountains, Swain County, North Carolina. ca. 1950. Published as Figure 25 in U.S. Geological Survey. Professional Paper 349-B. 1963.
