|Here be the story of Dungeon Rock.|
|Beside Dungeon Rock, the burial location of one of the two men who excavated the cave.|
June 21, 2016 UPDATE: And, six years after I published the above, I finally found my way to Hiram Marble's grave in Bay Path Cemetery in 88 Main Street, Charlton, MA, about 70 miles from Dungeon Rock. He's buried with his wife and his epitaph is quite [super]naturally, "Hiram Marble Passed to Spirit Life Nov. 19, 1868."
