Abstract:

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data were formerly available from the Montana State Library web site but were removed because they are potentially out of date.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.

Surface geology from a 1:12,000 scale Anaconda Co. map. Tics used to digitize were converted to UTM with the ACS2UTM program. This coverage still needs to be adjusted to correct UTM coordinates. The source map was brittle blueline paper, with geologic units shaded with colored pencil. The item which identifies the geologic units, GEOTYPE, has 10 added to its value if the source map was unclear as to what color the unit was shaded.
