Digital mining claim density map for Federal lands in Utah: 1996Entry ID: USGS_OFR_99_407
Abstract: The digital map was developed to document mining claim activity
on federal lands in Utah 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.
The mining claim density data of federal lands in Utah are combined with
the ... digital Utah Public Land Survey (PLS) to create a digital map of the
density of mine claims in Open-File Report 99-407.
The mining claim density data of federal lands in Utah was one of
13 western states released in Open-File Report 99-325. The database for
Utah was converted to an Arc/Info file and connected with the PLS by an
As stated in OF 99-325, "The 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. The database
quantifies the status of mining claim activity for federal land in the
State of Utah for 1996 and includes information on past mining claim
activity on federal land since 1976. It 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".
Combining the database with a digital PLS coverage of Utah enables a user
to spatially display the mine claim data as a digital map and compare it
with other spatial themes.
This data is in Arc/Info 7.1 format

Access Constraints None
Use Constraints Users should contact the BLM for current data. 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. This digital map is not meant to be construed as a legal representation of mining claim boundaries. The PLS data is assumed to be from 1:100,000 scale base maps. The map should not be ... used at scales larger than 1:100,000. The user must obtain current information on mining claims from the Utah State Office of the Bureau of Land Management for the area of interest since the mining claim density data is 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 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.
