The cave pictured here is Sea Anemone Cave near Acadia National Park, in Maine. The photo below was taken by me in 1974, a 25-year-old camper with a brand new twin-lens Mamiya C330 medium format camera that I used for black and white landscapes. An Ansel Adams disciple all the way!
I traveled to Acadia again this summer, um, a little bit older, and once again sought out Anemone Cave. The National Park has removed the cave from all maps and literature because too many times the Coast Guard was called out to rescue folks like me when the tide caught them inside the cave. I found the cave but unfortunately (or fortunately) the tide was already coming in, so I could only gaze from the cliffs above.
