ORONO — U.S. Interior Secretary Ken Salazar is visiting Maine to highlight the economic benefits of outdoor recreation and learn more about offshore wind generation research in the state.

Salazar is being joined by U.S. Senator Susan Collins during his visit, which will take him to Freeport, Orono and Millinocket.

Following a visit to L.L. Bean’s flagship store in Freeport, Salazar and Collins will join state officials for a tour of the University of Maine’s Advanced Structures and Composites Center. During the tour, participants will learn about the state’s deepwater offshore wind energy potential.

Later in the day, Salazar will travel to Millinocket to hear what the public has to say about creation of a new North Woods National Park east of Baxter State Park and adjacent to the Penobscot River.
