Geologic hazards to mankind exist in many parts of the world. Landslides, mudflows, earthquakes, and debris avalanches are serious problems that must be considered carefully by qualified personnel when man develops land use patterns for an area.

Wrightwood, a small community in southern California, is an excellent example of the devastating efforts that can result when geological engineering problems are not sufficiently understood by land developers and co-ordination governmental bodies.

This project report suggests that: (1) the geologic hazards of southern California are of considerable magnitude, (2) that considerable additional geologic investigation of these hazards is a real necessity, (3) that more communication from the engineering must be transmitted to those county, state, and local authorities responsible for protective action to cover the needs of the average citizen who desires to live in areas of extensive geologic hazard, and (4) that addition of governmental legislation necessary to promote this communication and protection.
