Trevithick Dredger Engine….progress

Finishing bits on the engine assembly.  The stuffing box, the gland, and a threaded plug in the throttle cylinder.  Throttle valve, stem direction valve,  piston and piston rod next.

Antarctic Weird.

Some of you might remember the Google Earth photos which I posted on Jan 6 2018.  “More Weird Stuff”.   The photo was from 1999 imagery.

Antarctica 6 Jan 2018 #2

This 21x7km black rectangular shape/object in Antarctica.  With the white reflections? white-out?.  And the track(?) leading from the south -east.   The satellite image was taken in 1999.  And I occasionally re-open Google Earth Pro to look at it, and wonder what it was.

Well guess what.  It has disappeared off Google Earth.   Nowhere to be seen.  Replaced with featureless white.

Suspicions aroused, I turned on the feature of Google Earth which allows the viewer to scan back and forth over the years.   I had place-marked the spot so I knew that I was in the correct place.  The “staircase” away to the north is still there.

While scanning the “spot” from December 2006, I noticed some odd lines.  Odd in that they were exactly parallel, exactly 1 km apart (you can measure things in Google Earth), and varying lengths, covering 1000’s of square kilometers.  then I noticed a little black dot on the computer screen.  It would not brush off.  Zooming in, it seemed to have a geometric shape, not at all like a natural feature, even pixellated.

I zoomed in and out.  If you look carefully (or better still, check this out on Google Earth yourself), you will see a white rectangular shape about 300m x 150m, irregular outline but quite angular and geometric, a black central shape, and a number of smaller grey shapes.  It is aligned almost exactly north-south.  It is bigger than an aircraft carrier.   Buildings?   Artifact?  Natural feature pixellated?

Buildings?   Well it is there, but whited out in the images Dec 2004 and 2005 but not after Dec 2006.

Artifact?  I thought maybe.  Then I looked around the vicinity.

Every one of those placemarks pinned by me, represents a similar but not identical object.  Some are clearer than the first one which I saw, particularly in the group under the “Leopold and Astrid Coast” label.  There are at least as many again, less clear, which I did not mark.

If you zoom into the above photo you will get the Google Earth co-ordinates to check this out for yourself.   Make sure that you bring up the December 2006 images.  The centre of the above cluster is the location my original “More Weird Stuff” object, but it is nowhere to be seen after 1999.

I have scanned around the rest of Antarctica and I cannot find anything else remotely like this.  Nor is there anything like this in other years/dates.

So, what do you think?  The images show 50-100 of these objects.  It appears to me that someone might have attempted to disguise the objects in the images by applying the thick parallel lines.

I have my own theory, but I will keep my ideas to myself.  For the moment…
