West Chichagof-Yakobi Wilderness

This Wilderness occupies the western portions of Chichagof and Yakobi Islands in the extreme northwest portion of the Alexander Archipelago of Southeast Alaska and is administered by both the Sitka and Hoonah Ranger Districts. Chichagof Island and, just to the north, smaller Yakobi Island, were named for a Russian admiral and a general, respectively. Western hemlock and Sitka spruce forests cover approximately 1/3 of the area, with muskeg, alpine, and estuarine vegetation making up the rest. The diminutive Sitka black-tailed deer is common here. Brown bears are frequently sighted, along with an abundance of smaller furbearing animals.
