"So........
I was looking through Charles Kenworthy's book about the Lost Dutchman. Imagine my surprise when I opened the book and saw HEART MOUNTAIN!"
No offense, but I just can't agree with the author. Not because of who it is, because I think the info is bogus.
How do we know these intaligos are Spanish in nature? Can anyone show other examples similar in the field created by the Spanish? I can think of many examples contributed to one dead/lost tribe or the other, but not to the Spanish. Rock piles, carvings on rock, mines, marked trails for man and beast, but nothing of this nature. So, if it is Spanish, why this site, why just this area?
I didn't say I agreed with Kenworthy so Im not offended.

I have 2 of his books and saw no need to buy any more. These were at Greg's house, so I checked them out. He, Kenworthy, seems to be a storyteller.
However, this mountain IS by an old Spanish trail and its not in the Sups. It is also near an old rail line used by mining companies, and an old mining ghost town. There are some famous 'coke ovens' out this way too........
That index card up there says something about finding someone else's gold and relocating it somewhere else eh...... From the mid 1930's too ta boot.... The book/pamphlet came out in the 1930's, but which Mexico was the author referring to? Modern day Mexico? 1858 Mexico? 1848 Mexico?
I dont think Kenworthy created these symbols though, if that's what you're implying. I have no guesses as to who did, but I have an idea of a timeline. Kenworthy totally fits in my timeline so, I cant rule him out either.
If you go to this place now (you will via a video here soon...) you'll see that the intaglios are almost gone. From what I can tell, they were still visable, albeit not like in the Kenworthy photo, in the 90's when Heart Mountain Project was bulldozing the center of the hearts. (Maybe that was 2000's...)
So from the time Kenworthy took his picture to now, the intaglios have almost completely disappeared except for the shrubbery and vegetation planted inside the hearts to make them stand out after a good rain. That makes me think that these intaglios were originally placed here, sometime not long before Kenworthy's photo. They surely arent from the 1700's. They would have been completely gone by Kenworthy's time, judging by the observable decay rate, UNLESS someone was actively maintaining them...and they would need maintaining. Its ground up rock strewn upon the ground. Wind, rain and gravity would make it disappear fairly quickly.
When did Kenworthy take that pic? Is it his pic? Is it an older pic he found or someone gave him? Did someone put these here to make US spin in circles? Did someone put this here to help them locate treasure? Is it all just for fun, something bored miners or ranchers do? I have surely made rock symbols on the ground for a laugh, but nothing near 700 feet long. Why would a team of men do this?
I dont know to all of the above.

It is fun though innit!
