Natural Attraction
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.
