“TRAP DOOR” in X3D Stereo

“Trap Door” is another popular anomaly, rendered here for the first time in X3D. Our context view once again reveals a debris-laden slope with many curious items to be seen throughout. Today’s attention focuses on the lower left corner where a clean angle presents itself.
Zooming into our detail view, we find a remarkably-symmetrical slab almost like a trap door, jutting out from beneath a boulder. Four things grab our attention: beautiful 90-degree angles, uniform thickness, a nicely-radiused corner on the right and regular, symmetrical notches down the left side. One finds similar notches on hinged covers, where the corresponding notches mate with the other piece, a longitudinal hole down the center running the length of the edge to accommodate the hinge pin.
A product of wind and sand? C’mon, get serious! This is a manufactured item, pinned to the sand when the overlying boulder rolled on top of it. I have ventured the label “trap door” because the boulder, its placement and the resting place on the rock to the left appear more purposeful than accidental. Is it perhaps a somewhat-hidden and sheltered exit from an underground lair? Could be.
More likely, it’s a remnant from the civilization(s) that once flourished on Mars; a stark reminder of what may await Earth if our tumultuous times find no resolution.

“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…
