Campbell Publication_Date: 05/25/1999 Title: Digital databases containing mining claim density information for Arizona, California, Colorado, Idaho, Montana, Nebraska, Nevada, New Mexico, Oregon, South Dakota, Utah, Washington, and Wyoming created from the BLM Mining Claim Recordation System: 1996 Edition: Version 1.0 Geospatial_Data_Presentation_Form: database Series_Information: Series_Name: Open File Issue_Identification: OF99-325 Publication_Information: Publication_Place: Menlo Park, CA Publisher: U.S. Geological Survey Online_Linkage: http://wrgis.wr.usgs.gov/open-file/of99-325 Description: Abstract: The mining claim density data is contained in 13 databases in Open-File Report 99-325. Each database was created from data obtained in March, 1997, from the Mining Claim Recordation System of the Bureau of Land Management. The data was analyzed, manipulated, and summarized into a database providing mining claim density information. Each database quantifies the status of mining claim activity on federal land within a state for 1996 and includes information on past mining claim activity on federal land since 1976. A database contains information identifying 1) the general location of mining claims within the Public Land Survey (PLS) system, 2) the number and type of claims (lode, placer, mill site, tunnel site) and 3) the status of the claims in 1976 (open is held, closed is no longer held by a claimant). Other terms used by BLM for closed claims are "Abandoned and Void" and "Void by Operation of the Law". According to BLM, new terminology for "Open" will be "Recorded" and for "Closed" will be "Terminated and Closed". There is one database for each of the following 13 states. Each database is in dBase 3 and ascii text formats: Arizona blm_az.dbf blm_az.txt California blm_ca.dbf blm_ca.txt Colorado blm_co.dbf blm_co.txt Idaho blm_id.dbf blm_id.txt Montana blm_mt.dbf blm_mt.txt Nebraska blm_ne.dbf blm_ne.txt Nevada blm_nv.dbf blm_nv.txt New Mexico blm_nm.dbf blm_nm.txt Oregon blm_or.dbf blm_or.txt South Dakota blm_sd.dbf blm_sd.txt Utah blm_ut.dbf blm_ut.txt Washington blm_wa.dbf blm_wa.txt Wyoming blm_wy.dbf blm_wy.txt Purpose: These databases were developed to provide mining claim information to quantify and qualify mining claim activity on federal lands in the western states. The information can be used in a geographic information system (GIS) and should be useful in researching interrelationships of mining claim activity with physical and social science concerns. The data are intended to be attached to a digital PLS of a state. The data are not to be considered as legal descriptions of the Public Land Surveys or of mining claims and their boundaries.

Use_Constraints: The U.S. Geological Survey makes no warranties related to the accuracy of the data and users are required to determine suitability of use for any particular purpose. These digital databases are not meant to be construed as legal representations of mining claim boundaries. The information in the database does not provide the legal location or status of individual mining claims. The user must obtain current information on mining claims from the State Office of the Bureau of Land Management for the area of interest since the mine claim density data is not current. Any hardcopies utilizing this data set shall clearly indicate their source. If the user has modified the data in any way they are obligated to describe the types of modifications they have performed on the hardcopy map. User specifically agrees not to misrepresent this data set, nor to imply that changes they made were approved by the U.S. Geological Survey.

Native_Data_Set_Environment: Windows95, Pentium PC, dBase 3 Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: The attributes of the mining claim data from BLM data, claims per section, do not represent the exact number of claims in each section. Some claims overlap into adjoining sections and/or townships. In order to count each claim only once, it was necessary to choose one section for each claim to be identified with. Therefore, the first section listed in the BLM database for a particular claim was chosen as the section the claim was counted in. The accuracy was tested by summing each category of claim in the mining claim database and comparing the sum to those from the original BLM database. The sums for each category matched. No attempt was made to determine the accuracy of BLM's database. Completeness_Report: None of the data from BLM was omitted. The data is considered complete for the purpose of determining mining claim density in this state. Logical_Consistency_Report: The data set is a derived subset of the original BLM data. No modifications to the BLM data were made. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: A claim may be within a section or it may straddle two, three, or four sections. In order to count each claim only once, it was necessary to choose one section for each claim to be identified with. Therefore, the first section listed in the BLM database for a particular claim was chosen as the section the claim was counted in. Interested persons should contact BLM for detailed information on mine claim locations and dimensions.

Source_Citation_Abbreviation: BLM MCRD, 1997 Source_Contribution: The BLM, through Cheryl Laudenbach, contributed the mining claim data of the State. The data included Process_Step: Process_Description: The detailed process steps are described in the U.S. Geological Survey Open-File Report OF 96-736 by Harry W. Campbell. An example of the use of the data is in Open-File Report OF 96-737 by Campbell and Hyndman. http://wrgis.wr.usgs.gov/open-file/ To summarize the process, the BLM data was brought into dBase, separated into 4 sub-databases, then massaged and summarized with several dBase programs to produce a mining claim density database. A unique field, MTRS, was created to enable the data to be joined to a digital PLS of a State. The State PLS digital file will also have to have the MTRS field created in order to properly connect the data. Process_Date: 1997-1998 Entity_and_Attribute_Information: Detailed_Description: Entity_Type: Entity_Type_Label: blm_XX.dbf Entity_Type_Definition: Summary of values for number and type of mining claims in each section. The data is tied to an MTRS code which represents the Meridian + Township + Range + Section. This code provides a unique identifier for each Section of the PLS. Entity_Type_Definition_Source: The Bureau of Land Management is the official source for PLS designations and surveys and for the mining claim data. 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: 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. Enumerated_Domain_Value_Definition: MM = the FIPS code for meridian. FIPS stands for the Federal Information Processing Standard. The codes for the meridians are: 06 - 6th Principal 07 - Black Hills 08 - Boise 14 - Gila & Salt River 15 - Humboldt 20 - Principal 21 - Mount Diablo 22 - Navajo 23 - New Mexico 26 - Salt Lake 27 - San Bernardino 30 - Uintah 31 - Ute 33 - Willamette 34 - Wind River 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 1/2 would be '_27.2'. The underscore represents a blank space. The 'TTT.2' represents the 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. The Oregon database also contains a 3/4 Range which is represented by 'RRR.3'. 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.
