How far...
Consider the Mississippi River and all of its navigable tributaries rivers like our
modern Interstate Highway system! and you will know reach of the Spanish.
As for the face you photographed, I see it of course, however I dont see any
confirmation that this is a verified monument. It would help you to save time
and a false trail, if you take more pics, at the proper time, high noon or so...
with you back to the sun...and look for possible confirmation marks, hoyos,
numbers, letters, shadows that contain symbols ect...
good luck on your search, be happy to look at more pics
