The Booming Out Ground is an old growth forest with Mud Lake Falls, two Indian portages, and a fascinating history of how it was saved from the chain saw. This is the area where the early log drivers established a collection point. The logs, tied together with chains acted as a corral of sorts so they could be towed down Spednic Lake. In 1994, a 488 acre parcel was brought to the attention of Land for Maine Futures Board and the State of Maine. Working together, it was conveyed to Inland Fisheries and Game as an ecological reserve to be saved forever.
