Geologic Mapping Program
Geologic maps provide information on the geologic structure and stratigraphy of a study area. They are a crucial component in the evaluation of energy, mineral, and hydrologic resources of an area.
Geologic maps published by WSGS geoscientists disseminate new data collected in the field and synthesize data from existing maps, reports, and investigations. WSGS geologists use a multi-disciplinary
approach to geologic mapping, including remote sensing, structural geology, stratigraphy, and geochronology to name a few. Geologists and Geographic Information System (GIS) specialists at the WSGS
use a variety of GIS software programs to publish digital geologic map products.
WSGS mapping is conducted at 1:100,000 and 1:24,000 scales. The agency is working toward mapping the entire state at the 1:100,000 scale. Areas of special interest are commonly mapped at 1:24,000.
Published geologic maps can be accessed on the Map Search page.

STATEMAP
Since 1994, the WSGS has been an annual participant in the National Cooperative Geologic Mapping Program
(NCGMP)—State Geologic Survey Mapping (STATEMAP) Component. The primary objective of this program is to establish the geologic framework of areas that are vital to the welfare of individual states.
Each state geologist determines the state's mapping priorities in consultation with a State Mapping Advisory Committee. These priorities are based on state requirements for geologic map information in
areas of multiple-issue need or compelling single-issue need and in areas where mapping is required to solve critical Earth science problems, such as land management or energy development.
- Mineral and Energy Resources—Create geologic and resource-based maps to evaluate current and potential leasable, locatable, and saleable minerals in addition to energy development; encourage responsible use and conservation of the state’s energy and mineral resources.
- Hydrogeology—Create new multi-scale geologic and hydro-geologic maps to assess, map, and investigate aquifer systems, recharge boundaries, flood zones, and erosion potential.
- Geologic Hazards—Create geologic maps, focused on geologic hazards, to assist city, county, state, and federal officials in siting, land-use planning, mitigation practices, and response preparation.
- New Mapping and Compilation—Create large-scale bedrock and surficial geologic maps to further scientific investigations, answer geologic questions, and expand the public’s understanding of Wyoming geology. Compile bedrock and surficial geologic maps at 1:100,000 scale, with the overall goal of statewide coverage.
