Geologic Mapping Program Funding

Geologic mapping in Montana is supported by State dollars and the U.S. Geological Survey’s STATEMAP and EDMAP Programs, components of the National Cooperative Geologic Mapping Program (NCGMP). The links below provide more information on the NCGMP programs and recently funded projects in Montana.


Funding for STATEMAP is awarded by the U.S. Geological Survey (USGS) through a competitive grant process that requires matching dollars from the State and completion of all funded maps within one year. All published STATEMAP products are available for free download from the MBMG website and also from the National Geologic Map Database (

Map areas are prioritized by a State Mapping Advisory Committee that represents Montana industries and universities, as well as Federal, State, and Tribal agencies. The Advisory Committee’s main priority is to complete geologic maps of all 30′ x 60′ quadrangles (1:100,000-scale) in Montana. Their second priority is detailed maps that focus on significant geologic issues, transportation corridors, or on areas where population development is occurring or anticipated. Staff geologists conduct new field mapping and work with existing geologic maps to complete new geologic maps in the priority areas.


MBMG geoscientists frequently collaborate with university professors and students on EDMAP projects. EDMAP is another component of the NCGMP and provides funding to universities for mentoring field geologic mapping projects.
