Utah Landslide and Debris Flow Maps

Database provides GIS shape files of landslides and debris flow paths and deposition zones in Utah. Data before 2007 is from a compilation of landslide mapping at a 1:100,000 scale. A more detailed inventory of landslides since 2008 is available at a 1:24,000 scale. Landslides that occurred before 1989 were added from published and unpublished references. Landslides that occurred from 1989-2007 were added from geologic maps and Utah Geological Survey investigations. Data compiled by the Utah Automated Geographic Reference Center.
