Headwaters Province - Idaho and Montana: Earth Science Studies in Support of Public Policy Development and Land Stewardship

The Headwaters Province project will provide geoscience data and interpretations to the Federal Land Management Agencies (FLMA) that are basic to sound policy and land-stewardship practices. U.S. Forest Service (USFS) National Forest and Bureau of Land Management (BLM) Resource Area Management Plans for the Headwaters Province are in revision, with completion dates from 1999-2003. USFS Regions 1 and 4 have made National Priority Requests for Mineral Resources Program (MRP) to provide interim products that help them meet their planning cycles. MRP is to provide geologic maps and topical studies to meet longer range goals of integrating geoscience into decision making. This project will emphasize development of digital geoscience data, GIS analyses, and interpretations to ensure that geoscience data are available for GIS-based science integration and planning. The inter-related goals of the project are at complimentary scales.

1. Provide digital geoscience databases for the province, at scales appropriate now and in the future, and applicable to local and regional questions.
2. Advance understanding of mineral resources in a geologic, economic, and environmental context.
3. Establish geologic context for ecosystem structure and function.
4. Use new understanding of processes and new GIS databases to develop GIS-based approach to forecast types and locations of near future mineral exploration and development.
