the development of the salmon fishing industry in alaska brought a cannery to chignik lagoon in 1882, about southwest of the future monument. the industry expanded, building fish traps in aniakchak bay by 1917. other traps followed through 1937, some operating until 1949. the alaska packers' association built a bunkhouse on aniakchak bay in the 1920s to house workers who maintained the trap and harvested fish during the summer months. at the same time, fur trappers arrived, this time to gather furs from inland mammals.
