Abstract:
Prime agricultural land along the Clear Creek floodplain, Colorado, attracted settlement in the 1850's but the demand for sand and gravel for 1900's construction initiated a sequence of events that exceeded previous interests and created the modified landscape and urban ecosystem that exists today. The Clear Creek valley corridor offers a landscape filled with a persistent visible and hidden reminder of it's past use.
The map sheets illustrate the Clear Creek landscape as a series of compositions, both at the macro view (in the spatial context of urban structure and highways from aerial photographs) and micro view (from the civic scale where landscape features like trees, buildings, and sidewalks are included). The large-scale topographic features, such as mountains and terraces, appear "changeless" (they do change over geologic time), while Clear Creek has changed from a wide braided stream to a narrow confined stream. Transportation networks (streets and highways) and spiraling population growth in adjacent cities (from approximately 38,000 people in 1880 to over a million in 1999) form two dominant landscape patterns. Mining and wetland/riparian occupy the smallest amount of land use acres compared to urban, transportation, or water reservoir activities in the Clear Creek aggregate reserve study area.
Four types of reclaimed pits along Clear Creek were determined: water storage facilities, wildlife/greenbelt space, multiple-purpose reservoirs, and "hidden scenery." The latter involves infilling gravel pits (with earth backfill, concrete rubble, or sanitary landfill) and covering the site with light industry or residential housing making the landform hard to detect as a past mine site. Easier to recognize are the strong-edged, rectilinear water reservoirs, reclaimed from off-channel sand and gravel pits that reflect the land survey grid and property boundaries. The general public may not realize softly contoured linear wildlife corridors connecting urban, industrial, and natural space were once mine sites too. Multiple-use water projects from exhausted pits appear to be the new millennium parks, providing water storage, passive recreation, and habitat restoration for the Denver metropolitan area. The public objects to mining yet enjoys the reclaimed mine sites as recreation and wildlife space.
Purpose:
With the high demand for Clear Creek water (less than half of the water passing through Golden flows into the South Platte River), high-cost of water rights (in the thousands of dollars per acre-ft), and potential for drought, reclamation of aggregate pits reflects society's values, community traditions, and scientific advances. Since the South Platte River and its other major tributaries are still undergoing this evolutionary process, the results of this investigation may be useful in understanding and planning their future.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
Data was were downloaded or entered and checked by the physical scientist and GIS operator. The attributes of this geospatial data set consist of text identifiers and numeric codes that indicate the identity of the natural or cultural unit or type of feature, and determine how each feature is colored or symbolized. To check attribute accuracy, a color check plot was visually compared to the physical scientist's original compilation. Discrepancies between the digital geospatial dataset and the original analog compilation were corrected as needed. This map has been thoroughly reviewed for conformity with U.S. Geological Survey editorial standards and stratigraphic nomenclature.
Logical_Consistency_Report:
Map elements were visually checked by the GIS operator for overshoots, undershoots, duplicate features, polygon attributes, and other errors. Automated (ARC/INFO) routines were also used to check the databases for polygon label errors, line or point attribution errors, sliver polygons, dangling arcs, intersection errors, and projection information. The map was reviewed by two other scientists for consistency with basic geologic principles and general conformity to USGS mapping standards.
Completeness_Report:
Some features were eliminated or generalized. A digital elevation map image is included.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Lines and points were digitized from topographic maps, from annotated aerial photographs, and from scientific literature. Most digitized positions on the map are estimated to have about 50-100 m horizontal accuracy.

In 1973, The Colorado Legislature passed House Bill 1529 which required that natural aggregate resources in the populous counties of the state be identified and mapped. In response to that Bill, the Colorado Geological Survey prepared potential natural aggregate maps for each of 271 1:24,000-scale quadrangles in the Front Range urban corridor and published those maps in Colorado Geological Survey Special Publication 5B. These maps have been digitized by the United States Geological Survey, repackaged into County coverages, and jointly published as a CD-ROM by the Colorado Geological Survey and the USGS as U.S. Geological Survey Open-File Report 00-9.
