This data set contains imagery from the National Agriculture Imagery Program (NAIP). The NAIP program is administered by USDA FSA and has been established to support two main FSA strategic goals centered on agricultural production. These are, increase stewardship of America's natural resources while enhancing the environment, and to ensure commodities are procured and distributed effectively and efficiently to increase food security. The NAIP program supports these goals by acquiring and providing ortho imagery that has been collected during the agricultural growing season in the U.S. The NAIP ortho imagery is tailored to meet FSA requirements and is a fundamental tool used to support FSA farm and conservation programs....

This dataset includes audiomagnetotelluric (AMT) sounding data collected in July 2018 in the Silverton Caldera complex, Colorado, in the Southern Rocky Mountain Volcanic Field, by the U.S. Geological Survey (USGS). Along with geologic mapping, airborne magnetics, airborne electromagnetics, and magnetotellurics, the USGS collected AMT data at 24 sites along four profiles ranging from 3 to 6 kilometers in length across the north-western structural margin of the Silverton caldera in Mineral Basin (MB01-MB05), across the south-eastern margin of the caldera along Cunningham Creek (CC01-CC05), within the caldera in Eureka Graben (EG01-EG05), and within the caldera along upper Cement Creek near the Gold King mine (GK01-GK09).

This dataset includes magnetotelluric (MT) sounding data collected in July 2019 in the Silverton Caldera complex, Colorado, in the Southern Rocky Mountain Volcanic Field, by the U.S. Geological Survey (USGS). Along with geologic mapping, airborne magnetics, airborne electromagnetics, and audiomagnetotellurics, the USGS collected MT data at 24 sites along five profiles ranging from 2 to 5 kilometers in length: across Red Mountain of the Silverton caldera, within the caldera in Eureka Graben, across the south-eastern margin of the caldera along Arrastra Gulch, across the southern margin of the caldera along the western margin of Kendall Mountain, and across the south-western margin of the caldera along South Fork...

This product consists of Adobe Acrobat .PDF format documents for 10surficial geologic strip maps along the Animas River watershed from itsmajor headwater tributaries, south to Durango, Colo. The Animas Riveroriginates in the San Juan Mountains north of the historic mining townof Silverton, Colo. The surficial geologic maps identify surficialdeposits, such as floodplain, and terrace gravels, alluvial fans,glacial till, talus, colluvium, landslides, and bogs. Sixteen primaryunits were mapped that included human-related deposits and structures,eight alluvial deposits, four colluvial deposits, one glacial deposit,one travertine deposit, and undifferentiated bedrock. Each of thesurficial geologic strip maps has .PDF...

This child item contains self-potential (SP) data collected over a small alpine wetland between Mogul Mine and Cement Creek located near Silverton, Colorado. Mine-impacted water is transported to Cement Creek via surface channels and groundwater through this wetland. The SP method measures passive voltages in the subsurface using a high impedance voltmeter with one fixed electrode at a base station and one mobile electrode. Strong self-potential anomalies have been associated with ore bodies and sharp redox fronts. Data were collected with an Agilent U1252B multimeter with STELTH3 Ag-AgCl Model SRE-011-SPB porous pot electrodes. Additional details are contained in the ‘readme.txt’ file within this directory.

During 1996 to 2000, the Bureau of Land Management, NationalPark Service, Environmental Protection Agency, United StatesDepartment of Agriculture (USDA) Forest Service, and theU.S. Geological Survey (USGS) developed a coordinatedstrategy to (1) study the environmental effects ofhistorical mining on Federal lands, and (2) remediatecontaminated sites that have the greatest impact on waterquality and ecosystem health. This dataset providesinformation that contributes to these overall objectives andis part of the USGS Abandoned Mine Lands Initiative.
