The Legends of Superior Trail connects the historic mining town of Superior with the Arizona Trail, 6 miles to the west. Along the way it passes through the high Sonoran Desert, the remains of the abandoned town of Pinal, and the riparian forest along Queen Creek, all while under the gaze of the majestic Picketpost Mountain to the south and Apache Leap to the east.

Phase I Environmental Site Assessment (ESA) for an approximately 59.9-hectare (148- acre) site along Tangle Creek in Tonto National Forrest in Yavapai County, Arizona (LX Bar Ranch).
This technical memorandum has been prepared to summarize results of drilling, construction, and testing at hydrologic test wells DHRES-12 and DHRES-13. Borehole DHRES-12 was drilled to characterize hydrogeologic conditions in the deep groundwater system in Cross Canyon, west of the Apache Leap escarpment, and to provide a monitoring location for the deep groundwater system during ongoing dewatering operations. DHRES-12 was abandoned prior to completion due to lost circulation and borehole instability. Well DHRES-13 was drilled at the same site to replace abandoned borehole DHRES-12.
Arizona hedgehog cactus surveys were conducted within the Resolution Pre-Feasibility Activities area in conformance with the monitoring required by the Resolution Copper Mining Pre-feasibility Activities Plan of Operations EA and the Forest Service's Biological Assessment and Evaluation.
The microbiological oxidation of iron and sulfur constitutes two key processes in mineral biotechnology. Both mesophilic and thermophilic bacteria have been described which can utilize inorganic compounds of Fe and S as electron donors (3, 5, 6). At present, although thermophiles are characterized by superior oxidation rates, only mesophilic iron- and sulfur-oxidizing acidophiles are used in large-scale leaching processes for metal recovery from sulfide ores.
