ON-006-17D Alluvial Fan Mapping of Select Quadrangles, Clear Creek County, Colorado (Data) – v20240115

$0.00

The CGS develops and provides a variety of geologic hazard maps for various state and local governments with land use and hazard mitigation planning in mind. The Upper Clear Creek Watershed Association (UCCWA) expressed concern about their preparedness for post-wildfire natural hazards and asked the CGS to more completely define alluvial-fan areas at risk for debris flows especially after wildfire events. Using available LiDAR technologies, both known and previously unrecognized alluvial fans were compiled, mapped, and defined. This map is part of a statewide effort to develop maps of alluvial fan areas in Colorado. Digital ZIP download. ON-006-17D – v20240115
