Knowledge of the distribution and type of landslides present in a region is one of the kinds of geologic information necessary for more effective land--use planning. This map provides such information. It is a preliminary map of known and suspected landslides prepared by stereoscopic analyses of high and intermediate level aerial photographs. Although prepared and published without the benefit of field checking for accuracy and completeness, this map is useful because it has quickly provided needed landslide information for immediate use in making land--use decisions.
