DISCLAIMER

The Oregon Department of Geology and Mineral Industries is publishing this map because the subject matter is consistent with the mission of the Department. The map is not intended to be used for site specific planning. It may be used as a general guide for emergency response planning. Maps in this publication depict landslide hazard areas on the basis of limited data as described further in the text. The maps cannot serve as a substitute for site-specific investigations by qualified practitioners. Site-specific data may give results that differ from those shown on the maps.

The data acquired, modified, and created for this project may not be a complete inventory of the features represented. Additionally, the landslides are based on published and unpublished reports and interpretation of topography using lidar data and air photos. This product is for informational purposes and may not have been prepared for or be suitable for legal, engineering, or surveying purposes. This report cannot replace site-specific investigations by qualified practitioners. Site-specific data may give results that differ from those shown on this map. See the accompanying report for more details on the methodologies used and the limitations of these data.
