Abstract:
  Mining Districts of Montana, developed by the Montana Abandoned Mines Reclamation Bureau. Based on a map of minining districts made in 1935, with some districts revised or removed, with addtional districts added. The districts were revised again in May of 1995.
  Mining districts were formed by associations of miners in a region who developed rules and laws to govern mining in the district. They sometimes established a monument to serve as the reference point for surveys in the district and created a description of the district boundary. Mining districts are no longer legal entities. Historical narratives describing the mining districts and their boundaries are available at http://deq.mt.gov/Land/AbandonedMines/linkdocs.
Purpose:
  This data was developed to facilitate the understanding of historical documents about mining. For some mines, the only record of their locations are descriptions of their situation within a mining district.

Data Quality Information:

Attribute accuracy report:
  Mining District names and alternate names have been reviewed by the Dept. of Environmental Quality.
Logical consistency report:
  Polygon and arc-node topology exist. Some districts include the boundaries of old districts that have been deleted, and there is no indication in the polygon representing the old district of which new district it belongs to.
Completeness report: The data set is complete.
Horizontal Positional Accuracy Report:
  Poor. Some coordinates appear to be as far as 400 meters from their correct postitions.
