Desert moons: You are among "The Few" who have noticed that !
This just a wild guess,
But!
It looks like a Half of a HEART, upside down ?
As you know, a "HEART", is the Spanish Treasure Sign for ORO!
Gold!
The heart's delight !
Actually, from this side view, you really can't see,
But! A tiny bit of the details
For Instance, about 1/2 down the head, lenght wise, is an "eye" !
&
From the top, looking down, you can see that the head is "Triangular"!
AND
Looking along the head, it is pointing, up hill, along a trail (To the East) Where, I hiked,
AND!
Where I found! The Second Turtle
A whole lot smaller, but, still, a perfect copy !!!!
