We just visited
Halibut Point State Park in Massachusetts.

Water-filled granite quarry with ocean beyond
Halibut Point was formerly a granite quarry. The quarried granite was used for large commercial projects, including some buildings in Boston and various shoreline projects in the late 1800's and early 1900's.

Side view of the quarry
There were once four granite quarries on Cape Ann. The quarry workers went on strike in fall of 1929. After the stock market collapsed a month later, these quarries never operated again.

Visitors Center and Observation Tower
The visitors center contains a museum about flora and fauna, as well as granite cutting history.
The tower on the visitors center must have spectacular ocean views. It was not open during our morning visit, but I believe it's open in the afternoon. It was built during World War II.

Scoop used for granite operations
Remnants of the granite operations are scattered throughout the park.
There are also hiking trails along rocky shoreline.

View from pile of scrap granite
On a clear day, you can see Mt. Agamenticus in Maine from the top of this 70 foot high pile of granite debris. We had a fairly hazy day so we could see about to the New Hampshire border.

Hiking trail and granite overlook
That's the pile of granite forming the overlook.

The shoreline has mostly fairly flat rocks, with tidepools, barnacles and rockweed.
We did see a sunbather surrounded by books and a snorkeler in a wetsuit.

Halibut Point is dog-friendly. Dogs must be on leashes.
Bailey would have loved it - but since it was so hot, we left him at home.

Water for humans and for dogs!

We stopped for lunch at the
Lobster Pool Restaurant, very close to the park.

To my New Hampshire tastebuds, the fried clam plate we shared had great clam taste and texture, but the fries were a little too greasy.
But with views like this, who's complaining??
