Wyoming's surficial geology is mapped at 1:500,000 scale, containing 577 separate landform and deposit descriptions. The layer was developed by the Wyoming State Geological Survey and Wyoming Water Resources Center for a groundwater vulnerability study. Compiled from aerial photography and existing maps, it was last updated in 1998.
Use Cases
- Assess aquifer vulnerability to pesticide contamination based on surficial geology features.
- Identify geological hazards like landslides and windblown deposits based on mapped landforms.
- Site new facilities or industries based on surficial geology in conjunction with bedrock maps.
- Locate shallow groundwater supplies and construction aggregate resources based on deposit descriptions.
- Refine regional hydrogeologic settings analysis based on Quaternary-age aquifer definitions.
Strengths
- 577 separate surficial feature and deposit descriptions provide detailed classification.
- Developed by state geological and water resource authorities for a specific statewide study.
- Compiled from aerial photography and existing maps, representing the first comprehensive map of Wyoming's surficial geology.
Limitations
- Last updated 1998-12-31 23:59:59.999000; freshness should be verified.
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
