rocky,
wonderful knife sign, shadow and sun style,,nice catch and on the soltice..lots of stuff hidden on that day gang...
I am fairly convinced you have the classic decoy, empty vault sign, invented by the jesuits at the later end of their golden age...

A very clever way to make all who find this spot think the goods are gone..but I have worked these in the supers..and the tell tale sign...is the signs around the decoy empty vault..for instance
1.knife pointing up
2.shadow heart pointing up
3.white dog, looking at the heart as he likes to do..pointing up
he has a triangle for an eye, so he is looking at the final layout..
4.owl rock incorporated looking very nice
5.the ubiquitous number "7" and this aint no campground 7
6.black shadow arrow, pointing out the 'chick'
7.chick, looking at the heart..the chick might mean a second smaller cache
confirmed nicely by all 7 elements..all telling you to go up...
I know you said nothing up there but sky.. it might mean up and over,
but for sure this site continues...up [perhaps north]
this is an omega, so your close...just up a ways..lol
hope this helps

decoy vault one of the last chapters in breaking the code
hidden in plain site as you can see, very well hidden only the kings men
could have seen thru this one..so the chances are... it may be intact~!
