1. Unit 8 – Coasts & Sea-level Changes (Cape Cod & Acadia) Acadia and surroundings. The yellow arrow points toward the fjord of Somes Sound in Mount Desert Island. The dotted line marks an area of interest for NASA and the National Park Service, and regions beyond have been blacked out. All pictures except this by C. or R. Alley http://www.nasa.gov/centers/goddard/earthandsun/nps_data.htmlhttp://www.nasa.gov/centers/goddard/earthandsun/nps_data.html Credit: NASA GSFC & Y.Q.

2. Unit 8 – Coasts & Sea-level Changes (Cape Cod & Acadia) The old metamorphic rocks (shown here) and granites of Acadia make dramatic cliffs. Floats for a few lobster pots are visible in the water.

3. Unit 8 – Coasts & Sea-level Changes (Cape Cod & Acadia) This beach at Acadia is one of the few in the area. Most of the sand is calcium carbonate--ground-up shell--because the Gulf of Maine is so amazingly productive of shells to be ground up by waves. The beach is far at the end of an inlet; the rest of the coast is dominated by bare rock.

4. Unit 8 – Coasts & Sea-level Changes (Cape Cod & Acadia) The Rockefeller-constructed carriage roads and their graceful bridges are well- loved at Acadia, which offers wonderful opportunities for bicycling. Dr. Alley and daughters Janet (left) and Karen for scale.

6. Unit 8 – Coasts & Sea-level Changes (Cape Cod & Acadia) Bass Harbor Head Lighthouse (left) and Portland Head Lighthouse (top), Acadia National Park and vicinity.

7. Unit 8 – Coasts & Sea-level Changes (Cape Cod & Acadia) Loons in rain, Seal Cove Pond, Acadia. The deep, glacially carved lakes of the island are outstanding for kayaking and canoeing.

8. Unit 8 – Coasts & Sea-level Changes (Cape Cod & Acadia) Jordan Pond and the Bibble Mountains. The rounded granite summits and U- shaped valleys are clear evidence of past ice.

9. Unit 8 – Coasts & Sea-level Changes (Cape Cod & Acadia) Even a rainy day can be enjoyable on the shore, as here at Ship Harbor. Notice the “beach” is composed of cobble-sized rocks.

10. Unit 8 – Coasts & Sea-level Changes (Cape Cod & Acadia) The no-beach granite coast of Acadia National Park in the fog.

11. Unit 8 – Coasts & Sea-level Changes (Cape Cod & Acadia) This herring gull is perched on the granite coast of Acadia.

12. Unit 8 – Coasts & Sea-level Changes (Cape Cod & Acadia) Ice flow as indicated by the red arrow smoothed this island, and plucked rocks off the lee or downglacier side to the right.
