The Tugamak Range dominates the southern reaches of this maritime landscape, rising abruptly from the northern coast of Unimak Island. Along the shoreline, Cape Mordvinof extends into the Bering Sea, marking a prominent point for navigation between the open water and the sheltered indentations of Urilla Bay. The map reveals a land defined by its isolation and dramatic elevation changes, where high ridges transition into the shallow waters of the Slime Bank offshore. Surveyed for the National Geospatial Program, this 2021 edition provides precise topographic data for this part of the Aleutians East Borough, showing the township boundaries of t61s r101w and t61s r100w across a terrain devoid of modern road infrastructure.
