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.
