Title: BLM REA NOS 2012 Active Mine Sites in the North Slope study area
Online Linkage: http://ardf.wr.usgs.gov/
Description:
Abstract: This data depicts the locations of active mines, prospects, and mineral occurrences on the North Slope. The original statewide data was the Alaska Resource Data File (ARDF), which was a subset of the National Mineral Resource Data System (MRDS) that has been specifically re-formatted and re-designed to better meet the needs of the local user community. Alaska Natural Heritage Program extracted active mines, prospects, and mineral occurrences from the ARDF and clipped to the North Slope study area.
Purpose: This dataset was developed for the BLM Rapid Ecoregional Assessment for the North Slope and represents the locations of active mines, prospects, and mineral occurrences in the North Slope study area.
Supplemental Information: Information for the Alaska Resource Data File is available: http://ardf.wr.usgs.gov/
