This geologic map was produced to compile and reinterpret published geologic information, and present the result of new geologic mapping in the Ray-Superior area. This data set serves as the basis for ongoing efforts to better understand the geologic history of this area, particularly with respect to the distribution and origin of mineral deposits.

The San Andreas fault zone has been a very significant source of major California earthquakes. From 1812 to 1906 it generated four major earthquakes of M ~7 or larger in two pairs on two major portions of the fault. A pair of major earthquakes occurred on the central to southern region, where the 1857 faulting overlapped the 1812 earthquake faulting. A pair of major earthquakes occurred on the northern region, where the 1906 faulting overlapped the 1838 earthquake faulting.

Increasingly, fault slip rates are being used to constrain earthquake recurrence relationships for site-specific probabilistic seismic hazard (ground motion) assessments. This paper shows the sensitivity of seismic hazard assessments to variations in recurrence models and parameters that incorporate fault slip rates.

This report is an addendum to the Surface Water Baseline Report prepared by M&A (2013) that includes detailed analysis and discussion of surface water monitoring results in the Resolution Project study area; Devils Canyon, Queen Creek, and Mineral Creek.

Public Land Order 1229 of September 27, 1955, which withdrew from all forms of appropriation under the public land laws, including the mining laws, certain national forest lands for campgrounds, picnic grounds, and roadside zones, is hereby modified to the extent necessary to open the following described lands to all forms of appropriation under the public land laws applicable to national forest lands, except under the U.S. mining laws.

This report provides the results of a noise monitoring study conducted by Arcadis at the Resolution Copper Mine (RCM) Lower Smelter Pond near Superior, Arizona. The study gathered data and assessed noise levels from construction activities associated with sludge removal from the pond.
