The large image image, port3.jpg, below shows
a cliff with a large ledge. In the midst of that ledge, also in lower enhanced image, is a rectangular structure, the lower floor of which is elongate. The right hand edge of this structure has a curved jointure between
the northeast wall and roof line. The second floor is more squared and turned at a precise 45º angle to the lower structure/ground floor. The
roof of this second floor is a large dark circle (black), which I can't help but compare to our own landing pads for helicopters atop tall buildings and on ship decks.
Perhaps this "building structure" by itself might not be overly indicative of a non-natural structure, however given the clearly evident black circle with an aburpt albedo (shading)change, this structure becomes much more
Up and to the right from this "building" structure is a culvert or open topped pipe, with fluids streaming from its end. These fluids can be seen blurred in this image from their motion. Erosion from the
fluids can be seen going down over the ledge and down the cliff face. Steam from these fluids seems to be emanating from the conduit and appears to be flowing west north/west direction, casting a shadow on the ledge area behind the
"building" structure itself.
There appears to be a structure stemming from the
first and second floor of the "building" which trails over the edge of the cliff, having stepped levels;a sort of enclosed stairway or chute
Below is an area immediately north of the above image which shows what I believe to be surface excavations similar to strip mining operations, with stepped pits and
ramped access into their depth. While this evidence of the "excavations" was not entirely conclusive and might,conceivably, have been from other more natural factors, perhaps even erosional, the conjunction of these "pits" with the apparent "building" structure gave me reason to examine more of the image in detail.
