So I was just looking around in Google Earth, when I find something.... weird. I don't know what it is, its perfectly circular and nature doesn't
do perfectly circular. Anyway, here it is:
Coordinates 52°50'29.99"N, 0°14'35.34"E
So, any thoughts? Things to note are that according to Google earth's altitude data, there is only about 8 metres ASL prominence on that.. thing.
Also, it measures it to be 200m across, with the middle bit 45 across. Also, to back up the altitude data there is almost no shadows on it.
Now, I know what you're thinking. It looks to be a very small Stratovolcano almost, doesn't it. Now, that is a) impossible for the area (no
earthquake activity, ever pretty much), b) far too uniform to be natural (well, look at Rainier, or Kilauea, or heck, anything natural), c) no flows
(well there aren't), d)no erosion on it (well, almost).
It's on the Ordnance Survey maps as well, but only at the 1:50,000 scale, where it only appears as a perfect circle. It doesn't appear on the more
detailed 1:25,000 scale maps. So I am really rather confused about this.
The only similarly shaped things to this that I've found on the satellite images are the nuke test craters in Nevada. I could almost say this thing
looks manmade.
Maybe I should email the BGS or OS people. They might know.
Edit, looking closer at the shadows makes it look like just a circular embankment with the middle the same mud as surrounds it. Interesting. that
definitely makes it seem man made, but who'd be crazy enough to build an earthen ring on a tidal sandbank?
