Shiloh,
they are not very plain, a real hodge podge, try taking chalk and very carefully mark the most promident of signs, I do see a "bird head" on the tree with the 77
on it, if they are Spanish then the bird head is real sign, that is telling you to look to the right of this tree for the next sign which will be above ground..the 77 is saying campsite twice, which is new to me, but there might be a spanish campsite to the right..c.it will have a stone cut chair or bed..some breastwork or forstacked rock work for protection, war,AND some trial markers or even an Alpha Monument to nearby mines,.so look close, take you time, anything thatertt looks likke a stack of rocks or boulders that has some , , owl, dog, t profile face, ect photos at noon or so,with your back to the sun, goodaluck, post any photos to send them to me at
rangler8@gmail.com for no strings elvautuation..in confidence..
