From vast stretches of black spruce forest to vernal pools and slow moving rivers, the Innoko National Wildlife Refuge is home to abundant wildlife from the smallest shrew to huge moose and everything in between. Established in 1980, this refuge located in western Alaska on the traditional homelands of the Athabascan people and is the fifth largest refuge in the United States. Fish abound, including huge northern pike in the coffee-colored waters of the Innoko River. The congressionally-mandated Innoko Wilderness Area includes much of the lower Iditarod River and many lakes and ponds.
