Photographs were taken to document and verify location of landslides in the Little North Santiam River Basin, Oregon. The photograph locations were identifed with cellphone GPS and plotted manually in the field using LiDAR-derived basemap. Photographs correspond to landslide deposits and scarp features based on UNIQUE_ID. This data set is one of 4 feature data sets included in a basin-wide landslide inventory. The landslide inventory is one of the essential data layers used to delineate regional landslide susceptibility. This landslide inventory is not regulatory, and revisions can happen when new information regarding landslides is found or future (new) landslides occur. Therefore, it is possible that landslides within the map area were not identified or occurred after the map was prepared. This landslide inventory is intended to provide users with basic information regarding landslides within the Little North Santiam River Basin. The geologic, terrain, and climatic conditions that led to slope failures in the past may provide clues to the locations and conditions of future slope failures, and it is intended that this map will provide useful information to develop regional landslide susceptibility maps, guide site-specific investigations for future developments, assist in regional planning, and mitigation of existing landslides.
