In each issue of Explorations, Mass Audubon’s bi-monthly enewsletter, we share a photograph taken at one of our wildlife sanctuaries along with a hint. Can you identify where it was taken?

Along the 12 miles of trails at this wildlife sanctuary, you can traverse over stone bridges, proceed through a boulder tunnel, and watch for beavers and muskrats emerging from the river that runs through the property. Those looking for a unique, after-dark experience can spend the night in a small rustic cabin.

Email your guess by January 15 and you could win a pocket field guide.
