The Montana aeromagnetic compilation map contains data from 65 separate aeromagnetic surveys, digitized maps, and previous gridded compilations. This map is an index to the flightline spacing of the original surveys. A tabular index (see index) provides a summary of the data sources. The raw data for all these surveys are available from the National Geophysical Data Center (NGDC), Boulder, Colorado.
