Historic image JLR�011 is part of the 'Historic photolab Images' collection; the topic area is 'Geophysical Review, 1939'. Location is Luray Quad (198B) (estimated). The image has the following description: 'Fig. 11 - This picture shows the valley of Passage Creek north of Seven Fountains, a cultivated lowland in the synclinal area between the two bounding ridges of the Massanutten Mountain mass. Rock structure is clearly revealed by distinct ridges, which are too low, however, to interfere seriously with cultivation. (38�50'N., 78�26'W.; Luray quadrangle, Va.) JL Rich 294-29. Aerial photo .'

Historic image JLR�003 is part of the 'Historic photolab Images' collection; the topic area is 'Geophysical Review, 1939'. Location is Thoroughfare Gap Quad (206C) (estimated). The image has the following description: 'Fig. 4 - Bull Run Mtn. Ten miles West of fig. 3. The gently rolling Tr lowland gives place abruptly along a fault line to parallel ridges of quartzite dipping steeply eastward. These are Cambrain [sic] quartzites resting on a series of pre-Cambrain volcanic rocks. The drainage runs through the ridges without deviation at Thorofare [sic] Gap; hence the streams have been superposed on the ridges from earlier and higher countries.

Historic image JLR�006 is part of the 'Historic photolab Images' collection; the topic area is 'Geophysical Review, 1939'. Location is Thoroughfare Gap Quad (206C) (estimated). The image has the following description: 'Fig. 6 - The first (?) outlier of the Blue Ridge, Big Cobbler Mtn., rises as an isolated, wooded cone about 750' above the gently rolling Piedmont Plateau. According to the geologic map the entire area shown is Catoctin volcanic rock; but the monodock (?) form of Big Cobbler Mtn. argues for the presence of something really more resistant than the surrounding rocks. (38�50.5'N., 77�57.5'W.; Thorofare [sic] quad., Va.) (35�51'N., 77�43'W.; Thorofare [sic] Gap. quad, Va.) JL Rich 294-22. Aerial photo...
Historic image JLR�009 is part of the 'Historic photolab Images' collection; the topic area is 'Geophysical Review, 1939'. Location is Bentonville Quad (209D) (estimated). The image has the following description: 'Fig. 9 - After crossing the south branch of the Shenandoah Valley we see the South Fork of the Shenandoah River, its remarkable meanders entrenched in the steeply dipping Ord. sh's. of the South Massanutten Mtn. The narrow, even-topped ridge crest of the mtn. is ground by steeply dipping Sil. qtzite, one of the most consistent ridge formers in the Appalachians. The Shenandoah has developed a considerable flood plain within its meandering trench. Here, however, it is cutting on bedrock and does not seem...

The image has the following description: 'Fig. 3 - Twenty-five miles west of fig. 2 the proportions woodland decreases abruptly along a N-S line, west of which is open, greatly rolling farmland with bright-red soil. (Newark Tr). There is a distinct N-S trend to the topography, suggesting steeply dipping sedimentary rocks. This view is three miles northwest of Haymarket.

The image has the following description: 'Fig. 15 - The wooded hills in the upper right of fig. 15 continue fig. 14 westward. Inspection on the ground indicated duplication of some of the ridge-making beds by faulting, probably of the thrust type. On the left side of the fig. 15 is an anticline, bordered on each side by a ridge of Oriskany sandstone, which can be recognized along the left edge of the picture, extending to the upper margin and thence back to the center. In the center foreground is the sharp, plunging crest of the anticline, revealed...

The image has the following description: 'Fig. 10 - This shows Massanutten Mtn., a compound, synclinal mtn. whose bounding ridges are tuscarora qtzite. The centrs lowland at the left of the center is developed Devonian shales. This mtn. mass separates the two branches of the Shenandoah Valley, which unite north of the mtn. as seen in the background.

The image has the following description: 'Fig. 12 - Immediately west of the western ridge of the Massanutten Mountain mass of the north branch of the Shenandoah River shows perhaps the most remarkable series of entranched meanders to be found anywhere. They are entrenched 100 to 150 feet in steeply dipping soft shales (Martinsburg) and their form, U-shaped, with straight, parallel sides and sharply curved ends, does not seem to have been explained. This view is just north of Woodstock. (38�53'N., 78�28'W.; Luray quadrangle, Va.) JL Rich 294-30. Aerial...
Historic image JLR�017 is part of the 'Historic photolab Images' collection; the topic area is 'Geophysical Review, 1939'. Location is Woodstock Quad (210A) (estimated). The image has the following description: 'Fig. 18 - This fig. continues the aerial cross section westward. The physiographic belts of Fig. 16 are seen on the right and are given the same lettering. In the lower right-hand corner the steeply dipping bedding of the ridge-making bed is clearly visible. Then come the synclinal mountains in the middle of the picture; a strike valley on the Catskill sh. and an anticline rimmed on each side by the ridge maker, and - as checked on the ground - exposing in its center the Middle Devonian sh.

The image has the following description: 'Fig 5 - West of the ridges of Fig. 4 is a rolling lowland developed on the volcanics, which weather into a peculiar, irregularly knobby topography, suggestive, under the late afternoon sun, of hammered silver. A vague, roughly N-S trend can be distinguished. This is almost 3 miles south of Marshall. (38�49'N., 77�52'W.; Thorofare [sic] Gap. quad, Va.) JL Rich 294-21. Aerial photo .'
