I wrote to the owner of the page - asked him what the picture was - here's the answer:
Hello all,
That, my friends, is a Leica Geosystems GPS Choke Ring antenna with a
debris shield which we hope will keep snow and ice out of it bolted to
an outcropping of granite in the Ford Range in Antarctica. It is east
of the Ross Ice Shelf near the coast (the bottom left red dot on this
image):

I was in Antarctica retrieving data from three GPS recievers in the Ford
Range which were part of a research project to determine if the tectonic
plates beneath the ice sheets in Antarctica were still active. The
project is over, and bottom line was that they are either no longer
active or are moving less than 5mm per year. Anyhow, I was sending
digital images home and my wife was renaming them based on what she
thought they looked like. She then passed them to Dominic to be posted
on the web, thus the image file name. :-)
Later,
Tim.

GPS... whooda thunk? i admit i had no idea what the thing was.
