High-Resolution Geologic Map of Palisade Quadrangle with Hazard Assessment

A 1:24,000-scale geologic map of the Palisade Quadrangle in Mesa County, Colorado, providing the first detailed view of the area. The map depicts 22 Quaternary surficial units, 5 age-classified pediment surfaces, and bedrock formations like the Mancos Shale and Mesaverde Group. Geology was mapped in 1996 and 1997 by contributors to the NASA Earthdata platform.

Use Cases

• Identify map units susceptible to specific geologic hazards like landslides, expansive soils, or flooding using the accompanying hazard table.
• Analyze the distribution and age of 22 Quaternary surficial units and 5 pediment surface classes for geomorphological studies.
• Assess landslide deposit locations and debris flow travel distances (up to 10 km) for hazard zoning and risk mitigation planning.
• Locate economic geology resources such as sand, gravel, and coal deposits referenced in the report's pamphlet.

Strengths

• High-resolution mapping at a 1:24,000 scale, a significant improvement over previous 1:100,000 and 1:250,000 scale maps.
• Comprehensive hazard analysis included, with a separate pamphlet detailing landslides, piping, gullying, expansive soils, and flooding.
• Detailed classification of surficial geology, including 22 Quaternary units and 5 age classes for pediment surfaces.

Limitations

• Data is temporally stale, representing ground conditions from mapping conducted in 1996 and 1997.
• Geographic scope is limited to a single quadrangle (Palisade) within Mesa County, Colorado.
• Specific technical details on data format, coordinate system, and digitization method are not provided in the description.
