The Kijik area (which includes Kijik Lake and the portion of the Kijik River that flows between the lake and Lake Clark) has been given some of the nation's highest designations of cultural importance. It is a National Historic Landmark and an Archeological District, one of only three areas in Alaska with both designations. Kijik is also a documented cultural landscape.
Kijik National Historic Landmark contains more than a dozen archeological sites, including a village abandoned at the beginning of the 20th century. The sites are affiliated with the inland Dena'ina Athabascan people who continue to live in the Lake Clark area.
