This summary report overviews a State of Arizona and U. S. Department of Energy funded drilling project to determine if near-term hot dry rock (HDR) geothermal potential exists in the eastern portion of the White Mountains region of Arizona. A 4,505 feet deep slim-hole exploratory well, Alpine1/Federal, was drilled within the Apache-Sitgreaves National Forest at Alpine Divide near the Alpine Divide camp ground about 5 miles north of Alpine, Arizona in Apache County (Figure 1). A comprehensive technical report, in two parts, details the results of the project. Part 1, Alpine1/Federal, Drilling Report, discusses the drilling operations,
logging program, permitting and site selection for the hole. Part 2, Temperature Gradients, Geothermal Potential, and Geology, summarizes the temperature gradients, heat flow, geothermal potential, and subsurface geology.
To help commemorate Arizona’s centennial on February 14, 2012, a centennial project was begun to inventory and promote the protection of historic cemeteries throughout the state. Historic cemeteries were chosen as the focus of a centennial project because they are important irreplaceable resources many of which are in danger of being lost through neglect, natural erosion, and vandalism. As the Arizona Centennial approached, it seemed appropriate that an organized statewide effort be undertaken to locate, inventory and provide guidance for the conservation and maintenance of these significant properties.
This contains two reports. The first is by authors from Statistical Research, Inc. that provides background information on the definition and application of the traditional cultural places designation under the National Historic Preservation Act. The second report is from the National Forest Service and expands on the first with examples of how traditional cultural places can be considered as part of land management planning.
