    • Description

      Have you ever spotted this shape on world maps? You will now ...
      It’s a sheer sided valley in the Sudan 3 x 3 degrees across and over 150 m deep !

      Fly over it with the ERS-1 altimeter and you only see flat desert.

      Comparing the GDEMs with the altimeter heights shows that the whole feature does not exist.
