This is a database of Uranium mines referred to as the Colorado (FS) Abandoned Mine Land Database.
The purpose of this data set is to become a part of a growing compendium of abandoned Uranium mine data for the Midwestern and Western United States.

Unknown.
Inconsistencies between county and coordinate information may be suspect.
Complete as per original data source.
A relatively small number points were located within study area, only one mine in the EPA data set matched one mine on the quadrangle maps. Point locations were off by more than 1,500 meters. Database is of poor quality in the areas tested.

URS Corporation
Internal GIS data index used for linking geographic location records to corresponding attribute data records in Arc/Info. ArcView shape files assume that attribute records are sorted by this index to match the correct polygon data record in shape file.
USFS
USFS State code, value=8 for all sites in Colorado.
USFS
Universal Transverse Mercator (UTM) Zone in which the feature is located. Value=13. Early in the project this value was included so that areas west of 108 degrees west longitude could be uniquely located. UTM coordinates are not unique but are tied to the zone in which they reside. The western boundary of zone 13, which covers most of Colorado, falls at 108 west longitude. It was later realized that all GIS data could be stored in zone 13 without danger of duplicating values, as a result it was decided to set this value to 13 in recognition of the fact that all GIS files are stored in UTM.
USFS
Unique X coordinate based on the X coordinate of the lower left corner of the 1000 meter UTM grid containing the majority of the inventory area. This value will range from about 138 to 765 depending on the longitude of the site.
USFS
Unique Y coordinate based on the Y coordinate of the lower left corner of the 1000 meter UTM grid containing the majority of the inventory area. This value will range from about 4000 to 4550 depending on the latitude of the site.
USFS
Unique identifier for densely mined areas where more than one inventory area may occur in the same UTM grid cell mentioned above. Values range from 1 to 3 usually and rarely 4 or more.
USFS
Number of mine features occurring in the inventory area.
USFS
Number of mine dumps and similar features occurring in the inventory area.
USFS
Primary name associated with the inventory area, or sites contained within it. Usually based on literature or map notations. When none were available then geographic names and relative references were used.
USFS
Secondary name associated with the inventory area, or sites contained within it. Usually based on literature or map notations. When none were available then geographic names and relative references were used. References to literature sources may also be included in this field.
USFS
Maximum radiation measurement obtained within the inventory area. Consult the hole and pile records for specific information about radiation measurements, units of measure and other relevant information.
USFS
Code representing the class of commodity mined in the area.
USFS
coal
uranium
metals
industrial material
Type of commodity mined in the area. Values vary depending upon the region. May include Gold, Silver, Gravel, etc.
USFS
County in which the inventory area occurs.
USFS
Numeric identifier of EPA defined water-cataloguing unit in which the inventory area occurs.
USFS
Name of the stream flowing nearest to the inventory area.
USFS
Name of the stream into which NEAR_STRM flows.
USFS
Has any reclamation been done in the inventory area.
USFS
True
False
Number of acres reclaimed.
