See process information, below. Purpose: Hyndman and Campbell developed the map to spatially research mining claim activity on federal lands in Colorado and to investigate interrelationships of mining claim activity with physical and social science concerns. This digital map is not to be considered as a legal representation of survey lines and corners or of mining claim boundaries. Supplemental_Information: Hyndman and Campbell's ORF 99-410 is the basis of this dataset. They used data obtained from the Mining Claim Recordation System (MCRS) of the Bureau of Land Mangement in March, 1997 for the 20-year period 1976-1996. For this report, claim density was linked to a public land survey grid and reprojected. See process information below.

The U.S. Geological Survey (USGS) makes no warranties related to the accuracy of the data and users are required to determine suitability of use for any particular purpose. This digital map is not to be construed as a legal representation of mining claim boundaries, nor is the data within any field considered reliable. In most cases, the data should not be used at scales larger than 1:100,000. The user must obtain current information on mining claims from the Colorado State Office of the Bureau of Land Mangaement for the area of interest because the mining claim density data are not current. The information in the database does not provide the legal location or status of individual mining claims. Any hardcopies utilizing this data set shall clearly indicate this source. If the user has modified the data in any way, (s)he is obligated to describe the types of modifications performed on the hardcopy map. User specifically agrees not to misrepresent this dataset, nor imply that changes were approved by the USGS.

Some claims overlap into adjoining sections and/or townships and ranges. In order to count each claim only once, Hyndman and Campbell choose one section for each claim to be indentified with. Therefore, the first section listed in the BLM database for a particular claim was chosen as the section the claim counted in. The accuracy was tested by Hyndman and Campbell by summing each category of claim in the mining claim database and comparing the sum to those from the original BLM database. No attempt was made to determine the accuracy of BLM's database. Completeness_Report: None of the data from BLM or from Hyndman and Campbell were omitted. The data are considered complete for the pupose of determining mining claim density in Colorado from 1976-1996. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: unknown. Because a claim may be within a section or may straddle as many as four sections, to assign it to only one section, Hyndman and Campbell assigned it to the first section listed in the BLM database.

Complete description of each attribute may be found in the metadata accompanying that report. Only the fields of interest to this report are described below: MTRS, NOLC, NOPC, NOMC, NOTC, TOC, NCLC, NCPC, NCMC, NCTC, TCC, TC Entity_and_Attribute_Detail_Citation: Anna B. Wilson Attribute: Attribute_Label: MTRS Attribute_Definition: A concatenation of Meridian, Township, Range, and Section of the PLS Attribute_Definition_Source: Bureau of Land Management Attribute_Domain_Values: Enumerated_Domain: Enumerated_Domain_Value: MMTTT.TDRRR.RESS__ Enumerated_Domain_Value_Definition: MTRS is an 18-character field which is a concatenation of meridian (M), Township (T), township direction (D), range (R), range direction (E), and section (S). The form of the field is MMTTT.TDRRR.RESS__. The last two spaces were included in the beginning of the study but were not utilized. MM = the FIPS code for meridian. FIPS stands for the Federal Information Processing Standard. The codes for the meridians are: 06 - Sixth Principal 23 - New Mexico 31 - Ute TTT.T = BLM Township designation as 'TTT.T' may include a fraction of a Township. For example, Township 1 would be '__1.0'. Township 27.5 would be '_27.2'. The '.2' is a 1/2 township. D = BLM Township direction may be North (N) or South (S). RRR.R = BLM Range designation as 'RRR.R' which may include a fraction of a Range. See Township (T) for example. E = BLM Range direction may be East (E) or West (W). SS = BLM Section number. For example, section 1 is '_1' and section 35 is '35'. Generally the highest section number is 36, but there are exceptions in several States.
