Abstract:

Tailings relocation areas along Silver Bow Creek between Butte and Warm Springs, and haul routes to remote repositories in Browns Gulch and Opportunity ponds. These data were created by Titan Environmental Services for the Montana Department of Health and Environmental Sciences (DHES) and are the second version of the data, created after review of the first version by DHES.

The data were submitted to the State Library as DXF files and were converted to Arc/Info coverage format. The archived data are saved in an ESRI file geodatabase to preserve the coverage annotation.

The polygons are all proposed tailings repositories. Lines whose SYMBOL attribute equal to 32 are haul roads, digitized so that their direction points towards the remote repositories.

Repositories whose REPOSTRY_ID values are greater than 1000 were removed from maps that were made using this data after September 1995.

These data were formerly available from the Montana State Library web site but were removed because they are potentially out of date. Please contact the Federal Superfund Bureau of the Montana Department of Environmental Quality if you want these data so they may tell you if newer or better data are available. If the data are not available from the Department of Environmental Quality, you may request a copy from the Montana State Library data archive.

Entity and Attribute Information:

Entity type label: Relocation_Polygons

Entity type definition: Polygon Feature Class

Attribute label: OBJECTID

Attribute definition: Geodatabase feature sequence number

Attribute label: Shape

Attribute definition: Feature Geometry

Attribute label: REPOSTRY_ID

Attribute definition:: Features whose REPOSTRY_ID value are greater than 1000 were removed from maps made after September 1995. The column was originally the coverage dataset ID Number. When this layer was in use, several polygons were un-selected graphically from the layer for maps made after September 1995. When the data were archived, these polygons were identified by adding 1000 to the REPOSTRY_ID.

Attribute label: Shape_Length

Attribute definition: Length of the feature's perimeter in meters.

Attribute label: Shape_Area

Attribute definition: Area of the feature in square meters.

Entity type label: Relocation_Lines

Entity type definition: Polyline Feature Class

Attribute label: OBJECTID

Attribute definition: Geodatabase feature sequence number

Attribute label: Shape

Attribute definition: Feature Geometry

Attribute label: REPOSTRY_ID

Attribute definition: Coverage dataset ID Number

Attribute label: SYMBOL

Attribute definition:: Symbol number, from the old plotter.lin Arc/INFO line symbol file, for drawing repository boundaries or haul roads.

Attribute label: Shape_Length

Attribute definition: Length of the feature in meters.
