The Indiana Dunes National Lakeshore comprised 8,330 acres of land and water when it was dedicated in 1971. Future legislation expanded the park to 15,000 acres.
Today the Indiana Dunes continues to serve as a popular tourist destination. However, while the land boundaries of the state and national parks are secure, less tangible but equally dangerous threats abide. The greatest perils currently facing the dunes are the spread of invasive species and the unknown impact of global warming. Luckily, dedicated staff and volunteers continue to work tirelessly against these forces to save the dunes for future generations.
