Bald Porcupine Island (seen in front of the ship to the right in this photo taken from Cadillac Mountain) is located in Frenchman Bay between Mount Desert Island and Schoodic Peninsula on the coast of Maine. A distinguishing feature is the breakwater that stretches outward. Without it, Bar Harbor would not have a safe harbor. Bald Porcupine Island is actually in Gouldsboro, Maine and part of Acadia National Park. Most of its 32 acres are covered with a mature spruce-fir and deciduous tree forest. Bald eagles and other nesting birds nest here so it is closed February 15 - August 31 of each year (or, until a park wildlife biologist determines that nesting is not occurring).

You will notice that, like most of the mountains and other land formations in this area, the northern side has a gentle slope whereas the southern side is less so. This was caused by the glaciers that migrated from north to south, shearing off the tops of the mountains and other land formations.

The island directly behind the cruise ship in the image above is Long Porcupine Island. The one to the left is Rum Key. The one behind Long Porcupine Island is called Stave Island, also part of Gouldsboro.

(Bald Porcupine Island is managed by a non-government conservation organization.)
