Friends of rock island supports the wisconsin department of natural resources to preserve rock island's rich history and wild spaces for future generations to come. We generate and facilitate many opportunities for over 50,000 visitors annually. All proceeds go directly to operating and maintaining rock island state park, including sustaining the environment of the park itself. One of the largest projects the friends of rock island supported was the restoration of the pottawatomie lighthouse. This light station was established in 1836, making it the oldest light station in all of wisconsin.
