The picture in post #16 is from the Titicaca site.
The pictures in posts #25 - 26 are from website linked in post #21. I don't know where they are from, I can't read it with enough understanding to decide. I originally thought he was saying they were from Titicaca but, I just don't know.
OK, I think the pictures in 25 & 26 are from the Basque discovery. The one with the crosses matches his English translation of the description. I looked at the website briefly, but did not find similar pictures, but my husband hurried me out of the office where I have the high speed connection. Very, very interesting.
