Joe:
Thanks for the info. Much appreciated.
It'll help,if and when I do get the chance to go,and I've been offered the use of an atv if I would rather ride. Should be able to tell if the work continues...or has been abandoned since 2006.
I had checked the BLM site,but didn't see anything listed for 2010 or 2011. I do remember seeing some fresh looking diggings/tailings higher up toward the north in some of the pics taken from the Cessna that I was shown.
Sounds like Larry and Roger were also wondering about the purpose of the bulldozer work on the hill.
Whoever made the claim,and especially erected the fencing,must have considered the hill to be a hot prospect.Doubt they could have missed seeing the markings,and may have thought they had some importance.Ditto for excavating across the Heart in particular.
I've posted one photo before,of a similarly sized triangle mostly made up of a dense growth of cholla.
I've assumed the triangle was natural,but it is in a location where I believe I should expect a triangle to be.But there is also a triangular flat area/bluff a few degrees to the left,from which I can look down at a big heart-shaped pile of rubble.
This photo was taken from the top of that pile.

Although you have decided that the Latin Heart did/does not exist,or is irrelevant or fake,I have not.
And if you look at he arrangement of the words "noto triangulum" (note triangle), and "fornix" (arch) on the L/H
.................FORNIX.................
............NOTO TRIANGULUM......
and compare it to what can be seen in this photo,perhaps you can understand why I believe I'm studying the same area as viewed by whoever made the stones,including the Latin Heart.
Also why I have been sharing some of what I myself have seen these past couple of years.
All of which matches what is on the stones, in similar fashion.
