Burns This database is an inventory of existing landslides and includes supplemental photos taken by staff geologists while performing landslide related field work. The landslide inventory is one of the essential data layers used to delineate regional landslide susceptibility. This inventory is not regulatory, and revisions can happen when new information regarding landslides is found or when future (new) landslides occur. Therefore, it is possible that landslides within the mapped area were not identified or occurred after the data was prepared. This data was prepared by following the Protocol for Inventory Mapping of Landslide Deposits from Light Detection and Ranging (Lidar) Imagery developed by Burns and Madin (DOGAMI Special Paper 42, 2009). The three primary tasks include compilation of previously mapped landslides, lidar-based morphologic mapping of landslide features, and review of aerial photographs. Landslides identified by these methods are digitally compiled into this database at varying scales. The recommended map/use scale for these data is 1:8,000. Each landslide is also attributed with classifications for activity, depth of failure, movement type, and confidence of interpretation. The landslide inventory is intended to provide users with basic information regarding landslides. The geologic, terrain, and climatic conditions that led to landslides in the past may provide clues to the locations and conditions of future landslides, and it is intended that this data will provide useful information to develop regional landslide susceptibility maps, to guide site-specific investigations for future developments, and to assist in regional planning and mitigation of existing landslides. <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>This feature class consists of polygons delineating landslide deposits (including debris flow fans and talus extent).</SPAN></P></DIV></DIV></DIV> Landslide, deposit, inventory None <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>This product is for informational purposes and may not have been prepared for or be suitable for legal, engineering, or surveying purposes.
