For those of you unfamiliar with the term, a “redoubt” is a temporary or supplementary fortification, typically square or polygonal and without flanking defenses. It is utilized as a stronghold for soldiers in both defensive and offensive encounters. Today’s Context View shows what I believe to be just such a stronghold right in the center of the image.
What caught my eye is the sunlight reflecting off the round portion, which looks a great deal like a tank’s turret.
Moving into the Detail View, it’s interesting to see that the tank analogy holds true: what could be treads are in the proper position and if you look closely, you can see what looks like a gun barrel angling about forty-five degrees to the viewer’s right.
To the immediate right are what appear to be steps. On further consideration however, they bear a striking resemblance to a gun emplacement of the type used with cannon orheavy artillery.
What seems to be a trench lined with protective revetments along the upper perimeter stretches out to the right. Is this indeed some kind of fortified area? The “turret” shows no clear signs of erosion, rust or battle damage and indeed, the sunlight reflects evenly off its smooth surface. If this is all just a trick of light and shadow, it’s a dandy!

“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…
