| Title | Trim line resulting from wave caused by landslide |
|---|---|
| Description | Trim line in spruce forest resulting from a wave created by a landslide triggered by the July 10, 1958, magnitude 7.2 earthquake on the Fairweather fault, S.E. Alaska. Right slip of several meters, which occurred at about 10 p.m., caused a large piece of the mountainside at the head of the bay to detach and slide into the bay. This generated a wave that first climbed the shoulder of the ridge (center of photo) separating the head of the bay from the main portion of the bay and cleaned the surface of trees and soil to an elevation of 1800 ft. above msl. The wave then moved out of the bay toward the open ocean in the distance creating the trim line at an elevation 200-300 ft. above msl. |
