Raw data were collected in Shenandoah National Park during summer 2012. Air and temperature data were collected using temperature loggers at several stations throughout the park. These data were used in the publication of the manuscript "Accounting for groundwater influence on headwater stream thermal sensitivity to climate change" through the journal Ecological Applications. Water temperature data were collected at all 78 reach locations during the summer of 2012 (23 June–7 September). Temperature was measured every hour with a logger.

Shenandoah National Park,
Shenandoah National Park, Virginia. Mud-lump breccia in the outcrop along the Appalachian Trail at the north end of the base of Little Stony Man Cliffs. Lumps of hard red argillite stand out as knots on the weathered surface. Light-gray streaks are irregular wisps of silvery phyllite. Matrix is fine- grained schistose greenstone.

In July 2016, July 2019, and March 2020, 318 seismic recordings were acquired at locations within Shenandoah National Park, Virginia, using MOHO Tromino Model TEP-3C three-component seismometers to assess depth to bedrock using the HVSR method. This method requires a measurement of estimate of shear wave velocity, which depends on the regolith sediment composition and density, for the conversion of measured resonance frequency to a depth to bedrock. Shear wave velocities were calculated for sediment in Shenandoah NP at locations where regolith thickness is known (e.g. at documented boreholes). The locations in this study were generally selected to characterize the depths to bedrock adjacent to streams monitored...

Shenandoah National Park, Virginia. Blue Ridge, viewed from the west. The flat fertile valley floor (foreground) is underlain by limestone of the Paleozoic age capped by terrace gravel. The low wooded foothills (middle distance) are underlain by steeply dipping quartzite and shale of the Chilhowee Group. The main mass of the Blue Ridge is composed of granitic basement rocks, but the highest part of the ridge is capped by greenstone of the Catoctin Formation. Photo by U.S. National Park Service. Figure 1, U.S. Geological Survey Bulletin 1265.

Shenandoah National Park, Virginia. Schistose greenstone along the Appalachian Trail at the base of Little Stony Man Cliffs. Here, a zone of breccia and schistose greenstone marks the boundary between the second and third flows above the base of the Catoctin Formation. The outcrop is approximately 3 feet high. Figure 7, U.S. Geological Survey Bulletin 1265.

Shenandoah National Park, Virginia. Columnar jointing in greenstone. Large column along the Appalachian Trail about 200 feet south of Little Stony Man parking area. The column is cut by cleavage which dips east, away from the observer. The segment of the coluiai above each cleavage plane is offset westward from the segment beneath as a result of movement during formation of the cleavage. Column is approximately 2 feet in diameter. Figure 9 (right), U.S. Geological Survey Bulletin 1265.

Shenandoah National Park, Virginia. Sandstone dikes in greenstone. Outcrop is on the north side of Skyline Drive at mile 47.3 on the south side of Hawksbill Mountain. Sandstone (light gray) displays faint subhorizontal bedding. Greenstone (darker gray) displays a dark chloritic border at the edge of the dike. The knife is about 3 inches long. Figure 11, U.S. Geological Survey Bulletin 1265.

Shenandoah National Park, Virginia. Franklin Cliffs, viewed from Big Meadows Campground, showing the prominent cliffs marking the outcrops of the second and third flows above the base of the Catoctin Formation. Note the change in attitude of flows near the fault. Figure 5, U.S. Geological Survey Bulletin 1265.
