Jordan Pond is an oligotrophic tarn in Acadia National Park near the town of Bar Harbor, Maine. The pond covers 187 acres (76 ha) to a maximum depth of 150 feet (46 m) with a shoreline of 3.6 miles (5.8 km). The pond was formed by the Wisconsin Ice Sheet during the last glacial period. Penobscot Mountain (1194 ft) rises to the west, while Pemetic Mountain (1247 ft) rises to the east. Two roche moutonnées known as The Bubbles (North and South) rise above the northeastern shoreline. The southern end is constrained by glacial debris and an artificial dam.
