The Arctic National Wildlife Refuge (open access)

The Arctic National Wildlife Refuge

The Arctic National Wildlife Refuge (ANWR) is an area rich in fauna, flora, and oil potential, where development has been debated for over 36 years. Current law forbids oil and gas leasing. This report discusses debate over whether or not to open the ANWR up for development and includes discussion of various legislative options under consideration.

Wilderness: Overview and Statistics (open access)

Wilderness: Overview and Statistics

The U.S. Forest Service established the first protected "wilderness area" under its own discretion in 1924. In 1964, the Wilderness Act established the National Wilderness Preservation System, reserved to Congress the authority to designate wilderness areas, and directed the Secretaries of Agriculture and of the Interior to review certain lands for their wilderness potential. The Act also designated 54 wilderness areas with 9 million acres of Forest Service land. Congress began expanding the Wilderness System in 1968, and today, there are 631 wilderness areas, totalling nearly 104 million acres, in 44 States.

Real-Time Monitoring of Field Measurements for Mine Design: Greens Creek Mine, Admiralty Island, Alaska (open access)

Real-Time Monitoring of Field Measurements for Mine Design: Greens Creek Mine, Admiralty Island, Alaska

Abstract: Researchers at the U.S. Bureau of Mines conducted field investigations at the Greens Creek Mine in southeast Alaska for the purpose of validating computer design of mining methods and assessing real-time monitoring capabilities. The field study required the application of new technology because of the remoteness of the study site, the need for timely acquisition of data, and a limited budget for instruments and data acquisition. Various sensors were installed to monitor rock mass deformation and strain, temperature, SO gas emissions, and blasting. Data were collected through a distributed personal computer network and high-speed modems. These readings were used to develop visualization models of underground metal mining operations and drift-and-fill mining and real-time graphics displays of ground conditions. Results of the field tests showed that it is possible to gather, process, visualize, and verify mine designs on a real-time basis.

Structure and Emplacement of the Magmatic Intrusions Beneath the Valley of Ten Thousand Smokes (open access)

Structure and Emplacement of the Magmatic Intrusions Beneath the Valley of Ten Thousand Smokes

The goal of this project was to provide constraints on the subsurface geometry of the vent, feeder conduit(s), and possible intrusive bodies in the Novarupta Basin, Valley of Ten Thousand Smokes (VTTS), Katmai National Park, Alaska. This research was designed to support the Katmai Drilling Project, a consortium involving the DOE, NSF, other government agencies, and several universities. Our work aimed at providing information to help guide site selection and identify targets for the drilling program. However, our research also has contributed to the understanding of silicic volcanic systems in general. Understanding the subsurface geometry of the vent is essential for accurately modeling the present thermal regime in the vent region and the eruption dynamics. Determining the origin of surficial fractures indicated the effect of compaction and consolidation of tephra and orientation of the depositional surface on fracture formation. Our research plan included (1) completion of a detailed topographic-structural map of surface fractures including spatial distribution and relative displacements; (2) numerical modeling studies that related surface fractures to major subsurface structures; and (3) interpretation of the origin of surface fractures in light of these model studies.
