In this great video Dakota Elder Joe Williams makes the connection between, although it is a subtle hint, that petroglyphs found in Minnesota depict land features found through aerial and satellite images to this day.
This confirms my observation that stones found on hunt site reflect topographical features found on that site and in areas to be traveled too from the site in which they are found.
This is why I encourage you to develop your observation skills to assist you out on the hunt site. Wisdom and Knowledge is still more valuable than even gold and silver. Since that Wisdom and Knowledge will bring the relic and treasure you seek.
I have been enjoying my research season this far, really having the luxury of sifting through the data documented this last year on the hunt. This video footage is on a major juncture and creek crossing on a productive cache site. I walked by this tree and worked around it this year, but only in researching the footage did I realize the same map I have found on surrounding rocks is also evident in the tree carvings and root manipulation. Check it out, what signs, symbols and clues are you missing on your hunts?
