The response of desert plant assemblages to disturbance was studied in Death Valley National Monument, California. Plant assemblages on debris flows, alluvial terraces, five abandoned townsites, and a pipeline corridor were measured to quantify recovery rates and to develop a model of change in desert vegetation.

The proposed conceptual model helps predict BSC distribution within intermontane basins to identify biologically sensitive areas, set reference conditions for ecological restoration, and potentially enhance arid landscape models, as scientists address impacts of climate change and anthropogenic disturbances.

The scope of this memo includes a critical evaluation of the setup, calibration, application and predictions of the M&A (2020a) Skunk Camp TSF groundwater flow and transport model, including the related inputs from the KCB (2020) seepage model.

This technical memorandum summarizes conceptual level sampling locations, sampling frequency, and laboratory testing to be conducted on tailings and the associated decant pond.

Location, Culture, and Transportation

The Superior mining area is in northeastern Pinal County, Arizona (Fig. 1). The area was officially organized as the Pioneer mining district but is better known as the Superior mining area.

Superior, the principal settlement within the area, in 1940 had a population of about 5,000, depending principally upon operations of the Magma Copper Company. The old town of Silver King, now largely deserted, was at the Silver King mine, in the northern part of the area shown on Plate I.

I am here today to advocate for my land, my culture, and my home, on behalf of the next generation and the generations that will come after me.

Response to GS-4: Provide input on alleged missed faults (lineament analysis) and whether they were incorporated into subsidence modeling.

The purpose of this process memorandum is to provide a summary of the geographic information system (GIS) spring coverage that SWCA created for the Resolution Copper Project (Resolution).
