Yukon Island Main Site, Archaeological site in Kenai Peninsula Borough, Alaska.
Located in outer Kachemak Bay, Yukon Island spans 2.5 square kilometers with steep cliffs rising 500 feet above the water level.
The site contains archaeological evidence spanning from 2500 BC to modern times, revealing multiple periods of human settlement through artifacts and structures.
Local Athabascan communities named the island Ni'ka, marking it as a central location where Athabascan, Yupik, and Aleut territories intersect.
The island requires special permission for visits due to its protected status as a National Historic Landmark and archaeological preservation site.
The 1964 Alaska earthquake caused the island to subside by two feet, leading to ongoing coastal erosion that continues to reveal archaeological materials.
