Description: Abstract: The CGS aims to provide geologic hazard susceptibility maps to state and local governments for use in their planning processes and mitigation plans. The Colorado Geological Survey (CGS) has begun developing landslide inventory and susceptibility maps for landslide-prone areas in Colorado. A lot of growth and development is taking place in the city of Boulder and the nearby towns in the county, near mesas and major drainages. Landslide deposits seem to be associated predominently with the hogbacks, incised drainages close the foothills, and glacial deposits in the subapline area of the county. The Landslide Susceptibility Map for Boulder County is part of a statewide effort to develop landslide inventory and susceptibility maps for landslide-prone areas in Colorado. A landslide is the failure and downslope movement of soil or rock due to the force of gravity exceeding the internal strength of the material. Methods: The landslide inventory was compiled by digitizing landslide deposits visible on 1-m resolution lidar datasets and high-resolution imagery, and joining it with previously cataloged landslide inventories from various published data sets and mapping projects. Please see accompanying text for more details.
