Magnetic Island is a small island located in Alaska, a state in the United States. It sits on the north side of Tuxedni Bay, which is an inlet of Cook Inlet. This island is special because of its unique features and ancient history.
The island gets its name from something cool: it has natural magnetism! This was discovered in 1951 during a geological survey. Scientists believe this magnetism comes from a mineral called magnetite, which is a type of iron ore.
Magnetic Island is surrounded by areas of mudflats. These mudflats are covered by water when the tide is high. The island's shape and the types of rocks found there have been greatly affected by two nearby active volcanoes. These volcanoes are Mount Redoubt and Mount Iliamna, both less than 20 miles (32 kilometers) away.

Discovering Ancient Life
Magnetic Island is very important for understanding human history. It holds an ancient site where people lived a very long time ago. Archaeologists have found evidence that humans lived here between 1800 and 1400 BCE. That's over 3,400 years ago!
What Archaeologists Found
In 2012, scientists dug up parts of the island. They found several layers of old materials. These layers showed signs of human activity. They discovered fire-cracked stones and hearths, which are old fireplaces. They also found stone tools. These tools are similar to those used by people from the Arctic Small Tool tradition. This tradition refers to a group of ancient cultures known for making small, finely crafted stone tools.
Why People Left
It is believed that the ancient people who lived on Magnetic Island eventually left. Scientists think they abandoned the site because of volcanic activity. The nearby volcanoes, Mount Redoubt and Mount Iliamna, are still active today. Their eruptions likely made the island unsafe for living.
A Protected Historical Site
Because of its rich history and important archaeological findings, Magnetic Island is now a protected site. In 2015, the archaeological site on Magnetic Island was added to the National Register of Historic Places. This means it is recognized as a significant historical place in the United States. Protecting it helps us learn more about the ancient people who once called this unique island home.
