About this map

Lava Lakes dominate the northern landscape of this remote section of the Tongass National Forest, illustrating a complex hydrological system where water flows through the Lava Fork. The map documents the high-latitude wilderness at the international border between the Canada United States of America, where topographic details show the transition from the alpine elevations of Albert Ridge down to the river valleys. The presence of the Blue River in the southwestern corner highlights the intricate drainage patterns characteristic of this glacial and volcanic terrain, providing a clear record of the area's natural state in the early twenty-first century. This survey is particularly useful for understanding the exact placement of the international boundary line relative to the sharp elevation changes of the surrounding ridges.
