From the topoView web site description: TopoView highlights one of the USGS's most important and useful products, the topographic map. In 1879, the USGS began to map the Nation's topography. This mapping was done at different levels of detail, in order to support various land use and other purposes. As the years passed, the USGS produced new map versions of each area. The most current maps are available from The National Map. TopoView shows the many and varied older maps of each area, and so is useful for historical purposes—for example, the names of some natural and cultural features have changed over time, and the 'old' names can be found on these historical topographic maps. This interface was created by the...

The Clifton-Morenci map area includes four 7.5’ USGS quadrangles: Coronado Mountain, Copperplate Gulch, Clifton, and Mitchell Peak. Descriptions of the Precambrian, Paleozoic, and Mesozoic rocks are primarily from Lindgren (1905a,b). The early Tertiary (Laramide) intrusive rock units are also described in detail by Bennett (1975), Menzer (1980), Preece and Menzer (1992), Griffin, Ring and Lowery (1993), Walker (1995), Phelps Dodge (1996), and Wright (1997). Hydrothermal alteration of the rocks of the Morenci porphyry copper deposit is well described in Lindgren (1905a), Reber (1916), Bennett (1974), Preece, Stegen and Weiskopf (1993), and Walker (1995). Descriptions of the Tertiary volcanic and sedimentary rocks...

This map shows areas of high-use recreation, including recreation sites compiled from USFS and BLM, recreation areas (including OHV areas), water-based recreation areas (selected from NHD waterbodies), water-based recreation travel corridors (selected from NHD flowlines), and land-based recreation travel corridors (selected from BLM GTLF within federal / state lands and national trails).

The GAP/LANDFIRE National Terrestrial Ecosystems represents a highly thematically detailed land cover map of the U.S. The GAP/LANDFIRE National Terrestrial Ecosystems dataset is produced by the U.S. Geological Survey in collaboration with the LANDFIRE Program. The GAP produces data and tools that help meet critical national challenges such as biodiversity conservation, renewable energy development, climate change adaptation, and infrastructure investment. Learn more about GAP and other GAP data (including protected areas and species habitat maps) at https://gapanalysis.usgs.gov.

A hydrologic model was developed as part of the Southeast Regional Assessment Project using the Precipitation Runoff Modeling System (PRMS), a deterministic, distributed-parameter, process-based system that simulates the effects of precipitation, temperature, and land use on basin hydrology. Streamflow and other components of the hydrologic cycle simulated by PRMS were used to inform other types of simulations such as water-temperature, hydrodynamic, and ecosystem-dynamics simulations.
