Description: In 1973, Colorado House Bill 1529 directed the Colorado Geological Survey (CGS) to complete a study of commercial mineral deposits to include sand, gravel, and quarry aggregate along the Colorado Front Range urban corridor. This study was completed in 1974 and the results were used to determine mineral resource areas to assist state and local governments in populous counties (over 65,000 people) with making planning decisions. The statute concerning areas and activities of state interest can be found in the Colorado Revised Statutes specifically, C.R.S. 24-65.1-101. Colorado statutes concerning mineral resources are included in C.R.S. 34-1-304 which are available at: http://www.lexisnexis.com/hottopics/Colorado/).
During the study, approximately 271 1:24,000 scale quadrangles were evaluated using photogeologic methods and available data within several counties including: Larimer, Weld, Boulder, Jefferson, Adams, Denver, Arapahoe, El Paso, and Pueblo. Douglas County was not included in the House Bill but was included in the study. The photogeologic maps were field checked during the fall and winter of 1973-1974. Maps and data prepared by the U.S. Geological Survey (USGS) for a Front Range Urban Corridor Study were also utilized in preparing 74 of the quadrangle maps (Schwochow and others, 1974). The results of the study were published in the following publication available on the CGS website (http://coloradogeologicalsurvey.org/):
• Schwochow, S.D., Shroba, R.R., and Wicklein, P.C., 1974, Sand, Gravel, and Quarry Aggregate Resources, Colorado Front Range Counties, Colorado Geological Survey, Denver, Colorado, Colorado Geological Survey Special Publication (SP) 5-A (43 pp., 3 Plates) and 5-B (420 pp.), http://coloradogeologicalsurvey.org/.
The study included three 1:250,000 scale regional maps included in the 5-A publication referenced above and detailed 1:75,000 scale maps included in the 5-B publication which were produced during the reduction of the original 1:24,000 scale field maps. Also, detailed 1:24,000 scale maps were distributed to the appropriate counties and cities within the project area. The maps provided were used by several Front Range counties to develop mineral extraction plans and for land use planning.
In 2000, the map data provided in the 1974 report were digitized and provided as GIS digital files by the Colorado Geological Survey in the following publication: Cappa, J.A., Sadlick J., Litke, D.W., McCormick, M.L. and Hiatt, C.S., 2000, Digital Version of the 197 Atlas 5-A, Colorado Geological Survey, Open File Report 00-09 (http://coloradogeologicalsurvey.org/). Additional GIS data files, similar to these, were also later published by the USGS (USGS, 2011). The 2000 CGS GIS files were provided in older versions of ESRI’s ArcGIS. Additionally, field names and codes used within the ArcGIS files were not descriptive making it difficult to determine the meaning of the field names and values. This project includes an update to the 2000 version of the GIS files associated with the digitization of the original 1974 study maps. These data files are included on an online ArcGIS interactive map available on the CGS website (http://coloradogeologicalsurvey.org/). This online resource also includes additional publically available layers associated with sand, gravel, and aggregate resources in Colorado. The following sections describe the updates to the 2000 original files as well as a description of each layer provided in the online ArcGIS interactive map.

Revised in 2018 Historical Quarry, Drill Hold, and Sample Locations, frir_aggx_point.shp – This file contains all of the point data associated with the 1974 study (Schwochow and others, 1974) including locations and information associated with drill holes, quarries, sample sites, sand/gravel pits, etc. The field name aliases were updated to be more descriptive and the actual values, which were all one or two letter/number codes in the original version, were updated with their corresponding descriptions. For example, the original field “TYPE” was renamed to “TYPE1” and the alias “Sample Type” was included. The values in this field were originally codes (e.g. D, P, Q, etc.) that referred to the descriptions in the metadata (e.g. D = drill hole, P = sand/gravel pit, Q = quarry, etc.). The codes were replaced with the actual descriptions provided in the 2000 metadata. It is important to note that some of the overburden and resource thickness values are recorded as “0” when the fields should actually be null. It was difficult to determine which fields needed to be null. See the resource and overburden thickness qualifier fields for more information.

Description: CGS IS-62 1981 Colorado Non-Metallic Mining Locations, Pre-1981 mines (All_pre_1981mines.shp) and other shapefiles (subsets of the shapefile referenced here) – This is an inventory conducted in 1981 of historic nonfuel nonmetallic mining operations (e.g. industrial minerals, sand, gravel, aggregates, etc.) within Colorado. The “All_pre_1981mines.shp” contains all the data points including areas not related to sand, gravel, and aggregate resources. Additional layers were included as subsets of this dataset and include sand, gravel, borrow, sandstone, silica sand, volcanics, clay and shale, crushed rock, decomposed granite, dolomite, limestone, and perlite. Other specific layers are available. The original publication is: Schwochow, S.D., Inventory of Nonmetallic Mining and Processing Operations in Colorado, Colorado Geological Survey Map Series 17, 39 pp, 17 Plates, http://coloradogeologicalsurvey.org/. The shapefiles included here were published in the digital version of the original publication published as: Keller, J.W., Phillips, R.C., and Morgan, K., 2002, Digital Inventory of Industrial Mineral Mines and Mine Permit Locations in Colorado, Colorado Geological Survey Information Series 62. In 2018, some of the field aliases were updated with more descriptive names.

Therefore, the additional layers were included as subsets of this dataset and include sand, gravel, borrow, sandstone, silica sand, volcanics, clay and shale, crushed rock, decomposed granite, dolomite, limestone, and perlite. The original publication is: Schwochow, S.D., Inventory of Nonmetallic Mining and Processing Operations in Colorado, Colorado Geological Survey Map Series 17, 39 pp, 17 Plates, http://coloradogeologicalsurvey.org/. The shapefiles included here were published in the digital version of the original publication published as: Keller, J.W., Phillips, R.C., and Morgan, K., 2002, Digital Inventory of Industrial Mineral Mines and Mine Permit Locations in Colorado, Colorado Geological Survey Information Series 62. Some of the field aliases were updated with more descriptive names.

Description: Colorado State boundary modified by the Colorado Geological Survey to provide an accurate digital representation of the state boundary. The original county data from which this coverage was created was developed by CO DOLA to support general mapping purposes. The State boundary in this coverage was created by merging county outlines that were digitized by the Colorado Department of Local Affairs (DOLA) from the USGS Colorado County topographic series (1979) scale stable 1:50,000 film positive composites. The digital boundaries were appended to create the statewide coverage. Includes the 1989 land transfer between Adams and Denver Counties for Denver International Airport and the 2001 formation of Broomfield County.

Description: The BLM land ownership shapefile was downloaded from the BLM website https://navigator.blm.gov/home. The BLM metadata is as follows: This dataset is subject to update daily. Process Steps and Publication Dates are not reflected in this metadata documentation. The purpose of these data is to provide a reasonably accurate depiction of who or what agency manages the surface of a given area of land. The data can be used for small scale (1:24,000 and smaller) analysis, cartographic products, GIS display, spatial feature discovery, spatial relationships (Man Made or Natural), These data support and assist in management decisions and planning. Shapefile Format –This data set is a result of compiling differing source materials of various vintages. Source material examples used to create and maintain dataset include: BLM 100k Surface Map Publications, Master Title Plats, Public Land Survey GIS Data (cadnsdi v.2.0), Field Office GIS Data, Compiled 24k USGS Maps, and Land Records. Ongoing updates are made. Credits: BLM, Colorado. Use limitations: These data are provided by Bureau of Land Management (BLM) “as is” and might contain errors or omissions.
