Points mark the locations of Maine inland landslides (landslides not related to coastal processes), delineated from Maine Geological Survey staff interpretation of lidar topographic data, air photos, and historical references. Features less than 0.5 acres and movement/erosion interpreted to be part of normal stream migration processes are generally not included due to scale. For coastal landslide information, see the Maine Coastal Bluffs and Maine Coastal Landslides datasets.
Extent of area disturbed by individual Maine inland landslides (landslides not related to coastal processes), interpreted and digitized from lidar topographic data (generally at 1:5,000 scale) by Maine Geological Survey staff. Features located along streams or rivers were likely altered and/or eroded by fluvial processes after the event, so the actual disturbed extents may be greater. For coastal landslide information, see the Maine Coastal Bluffs and Maine Coastal Landslides data sets.
