Magnetic Island (Alaska)

Magnetic Island is a small island on the north side of Tuxnedi Bay, an inlet on the lower west side of Cook Inlet in south-central Alaska. The island is surrounded by mudflats that are under water during high tides. The island got its name from the presence of magnetism (believed due to magnetite) identified during a geological survey in 1951. Its shape and geology are heavily influenced by Mount Redoubt and Mount Iliamna, two active volcanoes located less than 20 miles (32 km) away. The island is most notable for its archaeological significance, which includes a prehistoric human habitation site which has been dated to c. 1800-1400 BCE. The sites consists of a series of depressions, which when excavated in 2012, yielded several layers of cultural materials, included fire-cracked stones and hearths, and stone tools stylistically associated with the Arctic Small Tool tradition. The site was presumed to be abandoned due to volcanic activity.[3]
