Bubble Rock

Bubble Rock sits on a granite ledge above a colorful fall forest in Acadia National Park.

Bubble Rock sits on the cliff edge above Jordan Pond, a 100-ton boulder ready to drop into view. It was carried by glaciers from Lucerne, Maine, about 40 miles away, and left behind as the ice melted. From here, Jordan Pond, Pemetic Mountain, and Penobscot Mountain frame the view.
