I could leave it like this, to believe how what you have seen is the treasure site shape that match with the Tayopa treasure map. But I 'm not a con man, so what seems like the treasure site is only a decoy well made by the Jesuits to lure those who know to read symbols but not the hidden meanings/messages in the maps.
There is a set of three maps of Tayopa which are very close related each other.
The one is the Dobie's map of Camino de Tayopa which shows the contour of the relief and where the mines are placed in the field, and ultimately this map is oriented N-NE to the top and cover about 1,8 x 1,3 miles.
The second map is the Tayopa treasure map which shows the shape/markings of the ground around the caches and where the caches are placed, and the third map is the map with the hidden messages which shows where is located the real treasure site in regards to the church. And that map is this:

In this map, the first hidden message is how the real treasure site is double in surface than the decoy ( the Subterania shape vs the " mission Franciscana " which could not play in a Jesuit movie ), the second message is how the " arrow N " in the middle of the map is only for the church orientation and not for where is the tresure site in regards to the church. The treasure site should be read like is to the west from the church taking in consideration how the most of the texts are oriented parallel to the top which in the most maps is the north.
And the third hidden meaning is the words written on the Subterania shape, which are written in the order that are placed in the field and in the Treasure map site. Here we should to take in consideration how the shape of Subterania from the map cover only the region of the " Puerta " from the treasure site map, because is talking about the door of the underground room. Like you can see in the GE image of the real treasure site, the church is located in the treasure site map ( and is at the base of the church's cross from the Dobie's map ), with the Subterania ( Puerta ) and the treasure site to be west from the church. The arrow from the treasure site map points toward the entrance of the Subterania which is to the right of the " Puerta ".
Now about the words written on the Subterania shape from the map:
Like you can see in the map, in the first line from the left are written the words " Puerta.Color.Canjara " which means " door/entrance grey colored " which is pointed by the arrow in the GE image.
In the second line is written " Subterania " of why the entrance would be for.
In the third line is written " Treno.4.Pilares " which means " four colums in line " and you can see them in the GE image next above the arrow's point, and in the fourth line is written " Plata.120.Librad " which means " Silver 120 lb " and is for material and the weight of the door which is written in the first line.

There is something else that you have to know about Tayopa mines. Because the decoy treasure site is half than the real one, they wrote the half distances for the mines than in reality. And this is not a legend.
