STATEMAP

Intro

STATEMAP is a competitive, matching-funds grant program between the state geological surveys and the United States Geological Survey for conducting basic geologic mapping. The program is one of three components of the National Cooperative Geologic Mapping Program (NCGMP). A broad-based stakeholder group comprises the Colorado Geologic Mapping Advisory Committee (GMAC) that prioritizes the areas for mapping. The GMAC sets ranked priorities for geologic mapping in Colorado. Each year the state geological surveys submit proposals to a national review panel for monetary awards up to $300,000. Each grant requires a 50/50, hard-money match. Colorado has historically been in the top five grant awards in the nation.

The CGS joined the STATEMAP program shortly after it began in 1992. Since that time, STATEMAP has helped support the production of more than 150 detailed quadrangle maps of bedrock and surficial deposits across 25 counties (Arapahoe, Chaffee, Clear Creek, Costilla, Delta, Douglas, Eagle, Elbert, El Paso, Fremont, Garfield, Jefferson, Lake, La Plata, Las Animas, Mesa, Moffat, Montrose, Park, Pitkin, Pueblo, Rio Blanco, Routt, Summit, and Teller). This geologic information is regularly incorporated into decision-making on a wide variety of local and countywide issues that include:

• protecting groundwater
• locating new municipal wells
• siting waste-disposal facilities
• identifying potential mineral resources
• protecting homeowners from geologic hazards
• addressing a broad spectrum of land-use concerns

The results of Colorado’s STATEMAP program are used by planners and decision makers at the state, county, and municipal levels of government and as the scientific basis for preparing:

• a statewide inventory of mapped landslides
• various mineral resource maps using CGS-mapped quadrangles
• a resource map of sand and gravel for Garfield County
• a geologic hazard map for Clear Creek County
• a post-wildfire debris flow map in La Plata County
• a geologic hazard map for Montrose County
• a landslide susceptibility map for the city of Colorado Springs, which has suffered losses of $75 million from landslides
• a Denver Basin aquifer map

Advisory Committee

CGS has a diverse and dedicated group of professionals advising us on our mapping program. The Geologic Mapping Advisory Committee (GMAC) sets the priorities for Colorado’s program by ranking the twelve, national STATEMAP criteria. Each year they rank our submissions to the competitive program.

Maps

ON-004-01 — StateMap Progression Map — shows the quadrangles that have been geologically mapped across the state, both USGS and CGS maps. Of Colorado’s approximately 1,800 7.5-minute quads, more than 500 have been mapped and there are usually around ten more that are in progress at any one time.
