The final draft was written after Mr. Voelgerf s return to his home in the Russian-occupied zone of Berlin. Difficulties such as a shortage of typing paper of uniform grade and the impossibility of adequate supervision and advice on matters of terminology, punctuation, and English usage account for certain details in which this thesis may depart from stand­ ards of the Graduate College of the University of Arizona. These details are largely mechanical, and it is felt that they do not detract appreciably from the quality of the research nor the clarity of presentation of the results.

  • Cultural Heritage the Mountains and Foothills of North Carolina Have Over Many Centuries Fostered a Rich Mosaic of Cultural Heritage
    Western North Carolina Vitality Index Cultural Heritage www.wncvitalityindex.org The mountains and foothills of North Carolina have over many centuries fostered a rich mosaic of cultural heritage. The birthplace of the Cherokee’s advanced early civilization, the region is home today to the Eastern Band of Cherokee Indians, which continues to preserve many facets of traditional Cherokee culture. Beginning in the eighteenth century, European and African settlers moved into the mountains. The relative isolation of mountain life helped these settlers refine and preserve many traditions, most notably handmade crafts, traditional music, and local agricultural practices. Today, these distinctive cultural legacies are celebrated as living traditions, providing employment to master artists and tradition bearers and drawing tourists from across the globe to experience the region’s craft galleries, music halls, festivals, museums, farms, and local cuisine. photo courtesy of Blue Ridge National this project has been funded by Heritage Area a project of Blue Ridge National Heritage Area Designation A National Heritage Area is a place designated by the United States Congress where natural, cultural, historic, and recreational resources combine to form a cohesive, nationally distinctive landscape arising from patterns of human activity shaped by geography. Currently, there are 49 National Heritage Areas across the United States, where each area shares how their people, resources, and histories come together to provide experiences that “tell America’s story” and to encourage the community to join together around a common theme and promote the cultural, natural, and recreational benefits of the area. In November 2003, Western North Carolina (WNC) was designated the Blue Ridge National Heritage Area in recognition of the region’s agriculture, craft heritage, traditional music, the distinctive living traditions of Cherokee culture, and rich natural heritage, and their significance to the country.

  • Ecoregions of New England Forested Land Cover, Nutrient-Poor Frigid and Cryic Soils (Mostly Spodosols), and Numerous High-Gradient Streams and Glacial Lakes

It is a relatively sparsely populated region compared to adjacent regions, and is characterized by hills and mountains, a mostly Ecoregions of New England forested land cover, nutrient-poor frigid and cryic soils (mostly Spodosols), and numerous high-gradient streams and glacial lakes. Forest vegetation is somewhat transitional between the boreal regions to the north in Canada and the broadleaf deciduous forests to the south. Typical forest types include northern hardwoods (maple-beech-birch), northern hardwoods/spruce, and northeastern spruce-fir forests. Recreation, tourism, and forestry are primary land uses. Farm-to-forest conversion began in the 19th century and continues today.

ARIZONA GEOLOGICAL SURVEY CONTRIBUTED MAP CM-99-B (31 pp., 1 Plate) Geologic Framework of the Catalina Foothills, Outskirts of Tucson (Pima County, Arizona) [Text and Legend to Accompany 1:24,000 Map] William R. Dickinson, Department of Geosciences, University of Arizona May 1999 Introduction and Purpose Past geologic maps and accounts of the sedimentary, geomorphic, and structural geology of the piedmont of the Santa Catalina Mountains in the outskirts of Tucson by Voelger (1953), Pashley (1966), Davidson (1973), Creasey and Theodore (1975), Banks (1976), Anderson (1987), Pearthree et al. (1988), McKittrick (1988), and Jackson (1989) raised questions about the sedimentary evolution of the foothills belt that were left open or unresolved. Multiple dissected alluvial fans and pediments overlie much older faulted and tilted strata to form Cenozoic sedimentary assemblages of considerable stratigraphic and structural complexity. As a contribution to improved understanding of urban geology in the Tucson metropolitan area, systematic geologic mapping of the piedmont belt was undertaken to establish the overall geologic framework of the Catalina foothills (~ 175 2 km ) at a common scale (1 :24,000). The area studied extends from Oracle Road on the west to the vicinity of Rinconado Road on the east, and from the Rillito River and Tanque Verde Wash northward to the limit of bedrock exposures at the base of the Santa Catalina Mountains.
