Publication_Date: 2012 Title: Geospatial database for regional environmental assessment of central Colorado Geospatial_Data_Presentation_Form: document Series_Information: Series_Name: USGS Data Series Issue_Identification: DS-614 Publication_Information: Publication_Place: Denver, CO Publisher: U.S. Geological Survey Online_Linkage: http://pubs.usgs.gov/ds/614 Description: Abstract: This dataset is a lithogeochemical map of the U.S. Geological Survey (USGS) Central Colorado Assessment Project (CCAP) study area. The approximately 20,800 square mile (53,800 square kilometers) area of central Colorado encompasses Pike, San Isabel, Roosevelt, and Arapaho National Forests in U.S. Forest Service Region 2 (Rocky Mountain); a substantial amount of land administered by the Bureau of Land Management; and several areas in the National Park System adjacent to these Forests. Polygons in this dataset were derived from a preliminary geologic map that was revised from approximately 150 1:12,000 to 1:250,000-scale theses and published geologic maps. The more than 500 rock units mapped on the preliminary geologic map were simplified into 18 discrete lithologic units characterized by common rock type and chemistry, or in the case of sedimentary rock units, by their depositional environment and composition rather than by age of the rocks. Sedimentary rock units were also sorted into carbonate-rich versus carbonate-poor lithologic units to assess acid neutralization potential. The lithogeochemical map was used as a criterion for selecting and evaluating watersheds in the study area. Selected watersheds were underlain by one predominant lithogeochemical rock unit, contained large hydrothermally altered areas, or had historical mining activity either present or absent. These watersheds were evaluated to assess whether disturbance or weathering of underlying rocks results in water and sediment geochemistry that affects aquatic ecosystems or human health. Purpose: Polygons in this dataset represent lithogeochemical units in the CCAP study area. The lithogeochemical map was used to target 229 watersheds for evaluation. The watersheds were assessed to determine whether disturbance or weathering of underlying rocks results in water and sediment geochemistry that affects aquatic ecosystems or human health. Supplemental_Information: The USGS conducted the Central Colorado Assessment Project (CCAP) from 2003 to 2008 to provide Federal, State, and local land management entities geoscience information to address issues related to urbanization of the Colorado Front Range Urban Corridor. Rapid population growth along the Front Range and in the CCAP region, which encompasses about 20,800 square miles (53,800 square kilometers) of central Colorado between the New Mexico and Wyoming borders (37 - 41 degrees north latitude), and from west of Denver to east of Vail, Colorado (approximately 104.8 - 106.625 degrees west longitude), has caused tremendous demand for natural resources and has created challenging land-management issues related to the wilderness/urban interface expansion. Regional CCAP data, including geologic, geochemical, geophysical, biological, and remote sensing data, were compiled to assess the availability of mineral resources; the geo-environmental effects of historical mining and wildfires; geologic controls on groundwater resources; and hazards such as landslides and flooding.

Logical_Consistency_Report: Polygons in this dataset were simplified from source maps which included 1:12,000 to 1:250,000-scale theses and published geologic maps, and preliminary versions of five 1:100,000-scale maps. All map content was reviewed by the authors using modern geologic criteria and concepts, however, the resolution and consistency of map information most likely varies with the scale of the source maps. Completeness_Report: Geologic maps were compiled and simplified for the entire study area, a 20,800 square mile (53,800 square-km) region of central Colorado. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The positional accuracy of polygons representing lithogeochemical contacts varies with the source and scale of the base material. Base maps published by the USGS are generally consistent with National Map Accuracy Standards. The positional accuracy of geologic contacts from other sources may be highly variable. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: Not applicable Lineage: Process_Step: Process_Description: Polygons in this dataset were compiled from approximately 150 source maps which included 1:12,000 to 1:250,000-scale theses and published geologic maps, and preliminary versions of five 1:100,000-scale maps. The map compilation was revised using modern geologic criteria and concepts to produce a preliminary geologic map. The more than 500 mapped geologic units were then grouped together into 16 discrete lithologic units characterized by common rock type and chemistry, or in the case of sedimentary rock units, by their depositional environment and composition rather than by age of the rocks. In addition to composition and mode of origin, sedimentary rock units were sorted into carbonate-rich versus carbonate-poor units to distinguish possible effects of acid neutralization if mines were found in the catchment. Boundaries between adjacent polygons of the same lithogeochemistry were dissolved to produce the final simplified map.
