Reconnaissance engineering geology of the Yakutat area, Alaska, with emphasis on evaluation of earthquake and other geologic hazards : coarse-grained surficial deposits (mostly in young moraines and associated outwash) underlie much of the Yakutat area close to deep-water Yakutat Bay ; earthquakes and related water waves are the prime geologic hazard; five very large earthquakes with magnitudes of 7.0-8.6 have shaken the area during the period 1893-1975 / by Lynn A.
