Cherni Island and Alma Island are the primary landforms recorded in this maritime survey within the Pacific Ocean. Located in the Aleutians East Borough, this area is characterized by isolated land masses and the navigational hazard of Clubbing Rocks. The map focuses on these remote outposts of the Aleutian chain, providing precise documentation of shorelines and topographical elevations at a scale of 1:25,000. Grid coordinates for t63s r87w and t64s r87w define the survey boundaries, capturing the spatial relationship between these islands and the open sea during the early twenty-first century.
