Interesting to note Reia that even the Luiza meteorite structure located in
'deep and darkest' Congo, and newly 'discovered/confirmed' by my good friend
Ludovic Ferriere,
http://news.nationalgeographic.com/news/2011/03/110308-meteor-impact-crater-found-confirmed-congo-ferriere-science/
was first described in a German geological report from 1919. Ludovic gets
the credit however for slogging his way to the structure and describing the
associated shatter cones, and establishing its meteorite credentials. Some
thanks however to satellite imagery.
