With water or not , I believe your " reading " was closer to what I have guessed . This canyon/rain drainage , in which you have found the treasure is the bigger in the region and would be the most appropriate to hide a treasure .
I have walked beside this canyon up and down few times searching for a clue which could be used in relation to recognize the treasure site again with no very much difficulty . I thought about a big rock which would be more stable clue and to be at about the related distance and not in the sight of the ship .
I believe I have recognized the site about 20 years ago . After the canyon make a bent to the left ( looking up ) there is a big rock at the left side of the canyon and opposite from this big rock on the other side are three big round flat shapes on the ground of about 3-4 meters each , with the grass on this shapes to be dried . I knew from the old treasure hunters how obove the place where is buried gold and if this is not so deep , the plants or the grass will not survive long time because of the radiation which emits the gold . So , these places could be recognized in the spring season like dried stamps on the green carpet .
I watched this shapes over the years and they remained dry . Also i have studied the ground if had any substance which could produce this dry situation but nothing was found on the surface .This three shapes are on private land but not in the sight of any house and could be not difficult to dig . But i kept the site secret for about 16 years , because i had not needs and I wanted to be sure how there was gold before I would proceed an attempt to dig it .
So , two years ago I speak to a trusted tresure hunter to bring his metal detector ( I don't have one because i use to work with maps and symbols ) and to give a look at this spot . He came with a long range tool instead a disc and was not effective to read the site . His tool's antenna turned all around . Also the tool showed the site that elhit29 mentioned . After we saw how we were not able to " read " the spot , we planned to come back soon with the disk . Untill now we didn't go there because we were not pushed by circumstsnces and we are taking the project very calmly .
In the picture below you can see the dry shapes ( in the yellow circle ) close to the markings that you made .
You did a great job too and i thank you again .
