Sticks and stones: a Blue Ridge Mountain retreat
Given a sloping wooded site in the Blue Ridge Mountains of North Carolina, the problem of the thesis project was to design a retreat that would fit the environment and the people that would inhabit it. It was a searching for the interdependence between the landscape and the building. Equally …

Testing the Origins of the Blue Ridge Escarpment
… by climatic shifts or tectonic rejuvenation. The Blue Ridge Escarpment, eastern North America's great escarpment, is no different. A number of hypotheses attempt to explain the Blue Ridge Escarpment. These include lithologic variation between Blue Ridge and Piedmont rocks, the distance to ultimate …

Aquifer Characterization in the Blue Ridge Physiographic Province
Existing models of the hydrogeology in the Blue Ridge Province in the eastern United States generally assume a simplified two-layered system consisting of shallow unconsolidated and relatively homogeneous and porous regolith with a water-table aquifer that slowly supplies water downward to the …

Prescribed burning for vegetation management on the Blue Ridge Parkway
… of vegetation. Ten scenic overlooks on the Blue Ridge Parkway were selected for treatment. The experiment is a randomized incomplete block design. Four permanent transects were delineated in each unit for vegetation sampling. Four one-by-five meter plots were sampled on each transect for the …

Impacts of adjacent land use on Blue Ridge Parkway costs
… the cost of providing recreation services on the Blue Ridge Parkway were modeled using cross-sectional linear regression techniques. Twelve Parkway segments and corresponding adjacent counties provided the study sample. Total and per visit annual costs were expressed as a function of segment …

Evaluating Preferential Recharge in Blue Ridge Aquifer Systems Using Saline Tracers
… an important factor in current models of Blue Ridge hydrogeology, should be evaluated on a local or regional scale for any water resources investigation, wellhead protection plan, or groundwater remediation project.

Pedogenesis and geomorphic implications of soils developed on Blue Ridge alluvial fans, Virginia
Alluvial fans along the western footslopes of the Blue Ridge province, Virginia range over a linear distance of at least 200 km and spread westward up to 4.8 km. Certain soils formed on the fans appear old and highly weathered. Little detailed physical, chemical, or mineralogical data is available …

Local effects of culverts on habitat features and fish assemblages in Blue Ridge streams
… river drainages) in Cherokee National Forest (Blue Ridge ecoregion), Tennessee, May-August 2008. Culvert-related effects on instream habitat and fish assemblages were measured at 10 stream sites: five sites contained culverts with artificial bottom substrates and five sites contained culverts …

Modeling the Effects of Forest Road Density on Streamflow in the Blue Ridge Mountains
… was calibrated for a 760 ha watershed in the Blue Ridge Mountains of North Carolina. The impacts of forest road density were evaluated by running the model using uniform input parameters but changing road densities. Road densities tested were 0.5, 1.0, 3.0, 4.3, 6.0 and 12.0 km km-2. Results …

Soils and soil clay mineral formation in the Virginia Blue Ridge and Piedmont provinces
X-ray diffraction studies of 29 Virginia Blue Ridge and Piedmont soil profiles and petrographic examinations of the parent rocks reveal that even after prolonged chemical weathering, physical and mineralogical differences exist between soil types which are due largely to changes in the parent rock, …

Age and petrogenesis of the Striped Rock granite pluton: Blue Ridge province, southwestern Virginia
… similar to those presently exposed in the Blue Ridge province. Isotopic data also suggest that it is unlikely that the Striped Rock granite formed by simple differentiation of a mantle derived melt. Of the many models proposed for the petrogenesis of A-type granites the models that are most …

Proximate Causes of Alternative Reproductive Tactics in Blue Ridge Two-Lined Salamanders (Eurycea cf. wilderae)
… a sex and within a species. ARTs are present in Blue Ridge two-lined salamanders (<em>Eurcyea</em> cf. <em>wilderae</em>) in the form of male polymorphism. Two male morphs exist: “searching” males and “guarding” males. Each phenotype has a unique reproductive ecology and associated discrete …

Physical Investigation of Field Scale Groundwater Recharge Processes in the Virginia Blue Ridge Physiographic Province
… with regional thrust faulting within the Blue Ridge Province. Recharge rates appear to be correlated to spatial variation in the hydraulic conductivity of the regolith, which has been influenced by weathering rates and the metamorphic and structural history of the underlying parent …

The Middle Ordovician Fincastle conglomerate north of Roanoke, Virginia and its implications for Blue Ridge tectonism
… relief had developed between the axis of the Blue Ridge anticlinorium and the trough of the Salem synclinorium by Middle Ordovician time. The Fincastle conglomerate is restricted to the northeast depression of the Salem synclinorium, south of the Southern and Central Appalachian boundary. …

Geology of the Humpback Mountain area of the Blue Ridge in Nelson and Augusta counties, Virginia
… square km area along the western flank of the Blue Ridge anticlinorium in central Virginia has defined three major rock groups: (1) the earlier Precambrian Virginia Blue Ridge Complex; (2) the Late Precambrian Catoctin Group; and (3) the Early Cambrian Chilhowee Group. The Virginia Blue Ridge …

Evaluation of ozone treatment, pilot-scale wastewater treatment plant, and nitrogen budget for Blue Ridge Aquaculture
Sustainable tilapia production at Blue Ridge Aquaculture (BRA) is constrained by availability of high quality replacement water. I developed a pilot-scale wastewater treatment system to treat and reuse effluent presently discharged. An initial study was conducted to determine the response of the …

Geology and Tectonic Significance of the Late Precambrian Eastern Blue Ridge Cover Sequence in Central Virginia
The Late Precambrian cover sequence in the Blue Ridge of central Virginia includes rocks of the Moneta Formation and the overlying Lynchburg Group. The Moneta Formation comprises arnphibolites, felsites and biotite gneisses that unconformably overlie the Grenville basement. The Lynchburg Group in …

Protecting Scenic Views: Seventy Years of Managing and Enforcing Scenic Easements along the Blue Ridge Parkway
… to examine scenic easements acquired for the Blue Ridge Parkway in the 1930's and 40's and to develop an understanding of the challenges faced by the Parkway in attempting to enforce the terms of scenic easements drafted nearly 70 years ago. The scenic easements acquired for the Blue Ridge …

Evaluation of Brook Trout (Salvelinus fontinalis) Introductions and Re-introductions Into Four Virginia Blue Ridge Mountain Streams
Approximately 100 brook trout were transplanted into each of four Virginia streams in September 2008. Garth Run and Kinsey Run were re-introductions, and Wildcat Hollow and Sweet Run were new introductions. Single pass electrofishing (EF) surveys were conducted with a backpack electrofisher five …
