Map showing geochemical characteristics of the North Fork Smith River Roadless Areas, Del Norte County, California, Curry and Josephine Counties, Oregon

The North Fork Smith River Roadless Areas are located primarily in Del Norte County, northern California, include small parts of Curry and Josephine Counties, Oreg., and cover parts of the Gasquet, Crescent City, and Chetco Peak 15-minute quadrangles. The areas encompass aproximately 39,400 acres of Six rivers National Forest and 950 acres of Siskiyou National Forest and extend from just north of the California-Oregon border southward about 6 mi to the town of Gasquet, Calif. (fig. 1).

Maps showing aeromagnetic data and interpretation for the Kalmiopsis Wilderness, southwestern Oregon

The distinctive magnetic properties of the major rock types in the Kalmiopsis Wilderness of southwestern Oregon facilitate interpretation of aeromagenetic data. The region is composed of tectonic slices of magnetic ultramafic, gabboric, and other ophiolitic rocks faulted against the realitively nonmagnetic Dothan Formation, the equivalent of the Franciscan Complex of Western California. The sharp contacts between these rocks are manifested in the data by abrupt contrases in the nature of the magnetic anomalies which provide insights into the structural relations of major geologic elements. Most individual anomalies in this area are caused by known geologic boundaries or topographic features; those that are not are of particular interest because they may reflect areas of increased or decreased magnetization associated with zones of minerlization.

Geochemical map and rock and stream-sediment data from the Wild Rogue Wilderness, Coos and Curry counties, Oregon

The Wild Rogue Wilderness is located in Coos and Curry Counties, southwestern Oregon and covers part of the Bone Mountain, Marial, and Agness 15' quadrangles (fig. 1). It is an elongate area, 19 mi by 0.8 to 3 mi (31 km by 1.3 to 5 km) and includes approximately 35,818 acres extending from the town of Agness northeast to Mount Bolivar. The area is characterized by several diverse geologic terranes described in detail by Gray and others (1982). This paper summarizes semiquantitative chemical analyses of 256 rocks for 23 elements and analyses of 40 stream-sediment samples for 33 elements as presented in Gray and Peterson (1982).

Mineral resource potential map of the Kalmiopsis Wilderness, southwestern Oregon

Under the provisions of the Wilderness Act (Public Law 88-577, September 3, 1964) and the Joint conference Report on Senate Bill 4, 88th Congress, the U.S. Geological Survey and the U.S. Bureau of Mines have been conducting mineral surveys of wilderness and primitive areas. Areas officially designated as "wilderness," wild," or "canoe" when the act was passed were incorporated into the National Wilderness Preservation System, and some of them are presently 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. The act directs that the results of such surveys are to be made available to the public and be submitted to the President and the Congress. This report discusses the results of a mineral survey of the Kalmiopsis Wilderness, Siskiyou National Forest, Josephine and Curry Counties, Oregon. The area was established as a wilderness by Public Law 88-577, September 1964.
