The Wilderness Act (Public Law 99-577, Sept. 3, 1964) and related acts require the U.S. Geological Survey and the U.S. Bureau of Mines to survey certain areas on Federal lands to determine their mineral resource potential. Results must be made available to the public and be submitted to the President and the Congress. This report presents the results of a geochemical survey of the Hells Hole Further Planning Area (RARE II) in the Apache National Forest, Greenlee County, Ariz. and the Gila National Forest, Grant County, N. Mex. The Hells Hole Further Planning Area (03138) was classified as a proposed wilderness and further planning area during the Second Roadless Area Review and Evaluation (RARE II) by the U.S. Forest Service, January 1979.

Geochemical sampling of the Bunk Robinson Peak and Whitmire Canyon Roadless Areas was completed in the spring of 1980. The purpose of the geochemical sampling was to determine if certain metals, and "pathfinder" elements in heavy-mineral concentrates and stream sediments are enriched beyond normal black-ground amounts. The enrighment of elemental contents above background amounts in these samples can be importatn clue to the presence of a potential mineral deposit. These geochemical investigations are of part of an intergrated mineral resource investigation of the Bunk Robinson Peak and Whitmire Canyon Roadless Areas that also include geologic mapping (Hayes, 1982) and an evaluation of mineral resource potential (Hayes and others, in press).
Widespread rainfall of 3 to 9 inches in the mountains area of Arizona and West-Central New Mexico during December 17-20, 1978, caused maximum known discharges on the Gila River in New Mexico and on several streams in Arizona. At Phoenix, the Salt River was the highest since 1920 but was only slightly higher than the flood in March 1978. The Agua Fria River was the highest since 1919. The floods caused 12 deaths and more than $150 million in damage. Damage of $51.8 million occurred in Maricopa County, Arizona. Ten counties in Arizona and three counties in New Mexico were declared disaster areas. Unusually high volumes of runoff occurred on the Salt, Verde, and Agua Fria Rivers upstream from reservoirs. Overflow from the reservoir systems caused flooding downstream. Storage in the reservoirs on the Salt and Verde River reduced the peak discharge of the Salt River at Phoenix from a potential of about 234,000 cubic feet per second to 126,00 cubic feet per second and greatly reduced the duration of the flood.

The Lower San Francisco Wilderness Study Area consists of a narrow strip 1-2 mi (2-3 km) wide between the rims of the San Francisco River canyon. The wilderness study area has a moderately high potential for geothermal resources, a low to moderate potential for base metal or precious metal resources in middle to upper Tertiary volcanic rocks, essentially no oil, gas, or coal potential, and a largely unassessable potential for metal deposits related to Laramide igneous intrusions in pre-Tertiary or lower Tertiary rocks that underlie the area. The contiguous roadless area, which borders the New Mexico half of the wilderness study area, mainly on the north side of the San Francisco River, has a low to moderate potential for molybdenum or copper deposits related to intrusive igneous rocks in the core of a volcano of dacitic composition at Goat Basin.
