Thank you OP for posting this.
Growing up in Arizona and traveling around the state extensively, I have never heard this story. My father was one of these treasure hunters. I would
spend weekends with my father heading out to old ghost towns in his FJ. Metal detectors beeping and digging through dirt, it was a great time and I
Southern Arizona has a rich history and a very diverse geology, read up on the beginning of "Gem and mineral show". Caves in Southern Arizona abound
and many are still kept secrets from the general population as so they will not be destroyed. My grandmother was friends with the family that kept the
secret of Kartchner caverns all those years.
La Tetera cave spanish forthe teapot was found and the location never released.
As for the original story, it places many clues on its location and your right. It is NOT in South Eastern Arizona.
Thanks to the Author for hiding
the clues in plain site to keep people from visiting the real area. Southern Arizona is not a walk in the park or a simple day hike, Desert heat,
rattle snakes, and terrain make it very formidable place. Many hikers and immigrants find themselves in a bind very fast in our unforgiving desert.
The portal is not an entrance to the spiritual gateway, it is portrayed as a time portal. From what the story said the time differential could be any
amount a time, 1 day to 3000 years?. Maybe the portals time differential depends on the strength of electrical storms. Southern Arizona has some of
the best electrical storms in the nation.
Think about this: All those stories of finding human skulls and artifacts that are anachronisms . This idea of time portals could be the clue how
people and items could end up in areas where they should not be within the given time period.
I for one will not be heading out looking for this portal any time soon. But, I had a discussion with my wife last night. I told her if I do, I will
pick a location to hide an item that could last 700 years if I should go missing, she should look in this location for this item. What item would last
700 years? A stainless watch she gave me? I only live 1 hour from the supposed portal location. Hmmm, finding it would be days, months even years.
The stories could hold some truth, I dont think at the time anyone would want to be known as the Crazy fool telling these stories in such a small
town. The population is still very low in these areas , This would help in the cohesion of the original stories.
