The vast expanse of the Pacific Ocean dominates this maritime survey in the Aleutians East Borough. This specific area of the North Pacific is defined by isolated topographic markers, notably the small landmass of Umga Island and the hazard of Rush Rock to the northeast. These features are critical navigational points in an otherwise open sea, captured here within the township and range divisions of t61s r90w and t62s r89w. The map provides a precise record of the shoreline and maritime boundaries as they existed in the early twenty-first century, offering a clear view of the relationship between the few emergent features and the surrounding ocean depths.
