About this map

Revillagigedo Island presents a landscape defined by an intricate network of freshwater bodies and drainage systems within the Tongass National Forest. Centered on the expansive Ella Lake, the topography reveals a series of smaller alpine and basin waters, including Loom Lake to the north and the clustered Gokachin Lakes. This portion of the Ketchikan Gateway Borough is characterized by steep elevations and glacial landforms, where Gokachin Creek and its smaller tributaries like Gokachin Cr carve through the timbered terrain.

Remote landmarks such as the Gokachin Tri survey point and the sheltered Basin Lake offer specific reference points for understanding the interior hydrology of the island. The area remains largely undeveloped, with no roads present, emphasizing the preservation of the wilderness within the national forest boundaries. The inclusion of Mesa Lake further highlights the varied lake types found at different elevations, illustrating the complex watershed that drains toward the Alaskan coast.
