There's something new on Spectacle Island: temporary visitors. Throughout the island's history, things that got there had a tendency to stay: bones of fish that Native Americans caught, quarantined smallpox patients, and three decades worth of trash.
But the island is now a public park, and the Harbor Alliance and Massachusetts Department of Conservations and Recreation are trying to bring life to it.
Here is a look at the island's past -- and what visitors can expect to see in the future.
