Our Context View includes the “Trap Door” presented earlier, seen directly under the target circle. But what is that lying in the sand above and behind this classic anomaly?
The Detail View shows what may be a tool of some kind, somet wo to three feet long. It’s rather like the T-square found in many workshops. The long bar has evenly-spacedi ncrements engraved on it, leaving the impression that the rectangular plate with the semi-circular end and the hole in the center is made to slide up and down, locking into each increment according to need. It looks like the upper end curves back toward the bar, but that may be just an illusion of light and shadow. The three evenly-spaced plates perpendicular to the bar are of uniform thickness, have right angles and holes and certainly seem to be an integral part of whatever this is.
Given the proximity of the “Trap Door”, perhaps this was part of the locking mechanism, or possibly a tool used in conjunction with whatever purpose the door served.
The desire to walk over, pick it up and give it a thorough going-over is almost irresistible.
Unless of course, you’re from NASA.

“SO, HOW DO I VIEW X3D STEREO?”
Simple! While viewing the stereo pair at a comfortable distance, gently cross your eyes (no eye-strain) until you perceive three images all the same width. The one in the center is in 3D. Just relax into it and your eyes will automatically bring it into focus. Once you have it, you will never forget how to do it. Kinda like riding a bicycle…
