-- "Explorations in Grand Canyon," Phoenix Arizona Gazette (April 5, 1909)
So begins an article that describes the discovery of a "great underground citadel" with its entrance in the Grand Canyon--a real American dungeon.
Ok, maybe not real--despite what you might read on the internet about sinister Smithsonian cover-ups. But it is a American, and has the makings of a great dungeon.
The byline-less article tells the story of G.E. Kinkaid (or Kincaid, in works of a more recent vintage) who's thumbnailed as "a explorer and hunter all his life" and said to have worked for the "Smithsonian Institute" for thirty years. Kinkaid was travelling from Green River, Wyoming, to Yuma, New Mexico, down the Colorado in a wooden boat. In the Grand Canyon, in what is thought by subsequent researchers to be Marble Canyon, Kinkaid discovered the entrance to a cavern "1,486 feet down the sheer canyon wall." This cavern "hewn in solid rock by human hands, was of oriental origin, possibly from Egypt, tracing back to Ramses."
An expedition under the "S.A. Jordan" (another figure whose existence is difficult to verify) started mapping the cavern in good adventurer-style. Highlights include two large chambers, radiating passages, assorted idols, mummies wrapped in bark, mysterious hieroglyphics, and a "grey metal" that baffled scientists, but resembles that most valauble of D&D coinage metals, platinum. And one other intriguing random treasure: "Strewn promiscuously over the floor everywhere are what people call "cats eyes', a yellow stone of no great value. Each one is engraved with the head of the Malay type." The whole 1909 article is helpfully provided here, rich with cool detail.
Even better, Jack Andrews, a researcher on the topic, offers a map in the article on his website:
I wonder what those "cat's eyes" stones will appraise for?
