Studies and reports of all primitive areas have been completed. Areas officially designated "wilderness," "wild," or "canoe" when the Act was passed were incorporated into the National Wilderness Preservation System, and some of them are currently being studied. The Act provided that areas under consideration for Wilderness designation should be studied for suitability for incorporation into the Wilderness System. The mineral surveys constitute one aspect of the suitability studies. This report discusses the results of a mineral survey of the Bob Marshall Wilderness, proposed additions to the wilderness, and the proposed Great Bear Wilderness, northwestern Montana. -I- MINERAL RESOURCES OF THE BOB MARSHALL WILDERNESS AND STUDY AREAS, LEWIS AND CLARK, TETON, PONDERA, FLATHEAD, LAKE, MISSOULA, AND POWELL COUNTIES, MONTANA by U.S. Geological Survey and U.S. Bureau of Mines Chapter A.

The total area covers about 2,580 sq mi (6,680 km ) of the rugged Swan, Flathead, Lewis and Clark, and Sawtooth Mountains; the wilderness covers about 1,480 sq mi (3,830 km ). The results of the investigations indicate that parts of the area have a high potential for natural gas and a low potential for oil.

The Flathead Lakers is a nonprofit, grassroots organization. Our organization was founded in 1958 and currently has over 1,500 members. We work to protect water quality in Flathead Lake and its watershed through education, advocacy and stewardship projects. Our beautiful lakes, rivers and streams, and the fish and wildlife that depend on them are part of what makes the Flathead such a special place and are a large part of its identity. The quality of the environment contributes to our quality of life and our economy. In fact, our quality natural environment has become a competitive advantage and a major force driving economic growth in Flathead County. The Flathead Lakers initiated the collaborative Critical Lands Project in 1999 to address concerns that rapid growth and development would damage lands and waters critical to maintaining the quality of Flathead Lake and its tributaries and the area’s quality of life. The Flathead Lakers coordinate the resulting partnership, the Flathead River to Lake Initiative (R2L), which includes representatives from federal, tribal, state, and local resource management agencies, land trusts, conservation groups and landowners.
