Rockport, Massachusetts
Halibut Point State Park
A granite quarry filled with water on a cliff edge above the Atlantic, tide pools on the rocks below, and forty miles of view to Mount Agamenticus in Maine on a clear day.
Researched from this park's own sources. Nobody's walked it yet.
Read this bit out
People cut this whole cliff apart for its stone and carried it away to build things somewhere else, and the enormous square hole they left behind filled up with water. There are pools down on the rocks with creatures living in them that get covered by the sea twice a day and do not seem to mind. And on a clear day you can stand here and see a mountain forty miles away in a completely different state.
