Now that I have gone there and looked for myself, the "object" appears on a mismatched boundary of two images. It appears that there is about a 5 mile wide stretch of "missing" data that the software tried to airbrush across.
Move along...there's nothing to see here.
What about the bunkers that look like enlarged shoe treads?
Just check this out and I’ll leave you alone:
Just north 83 miles, in a mountainous area (68 deg 56 31.14 S, 88 deg 00 21.68 E) is a grill type structure in the mountains.
Looks to be about 1.5 miles long and .5 mile wide. Looks like the indentations of the edge of a giants astronaut boot.
Now if you think that this is software airbrushing or aerial stitching, then my efforts have failed today.
