How are you going to say “Happy Birthday” and celebrate the founding of Acadia National Park on July 8, 1916, as Sieur de Monts National Monument?

George B. Dorr’s spirit lives on in this historic photo at Sieur de Monts Spring at Acadia National Park.

Give thanks to park founder George B. Dorr, the staff and volunteers at Acadia National Park and the countless others that have made Acadia what it is?

Make a donation to Friends of Acadia?

Take a hike along one of the more than 125 miles of historic trails, or bike along the 45 miles of carriage roads donated by John D. Rockefeller Jr.?

Buy a memento of your visit from Eastern National, either at the bookstore at Hulls Cove Visitor Center, or online (special discount of 17.76% – in honor of year of our nation’s founding – see ad to the right, ends July 10), and help the nonprofit support the park?

Or how about post a birthday message on this blog, or upload a favorite Acadia photo to our Facebook account?
