Thanks again, Marcel! A nice site, and although these other islands 
are not new to me, it is only the second time that I read about the 
islands Tierra and Mar here. The first time was on a radio amateur 
site of a Mr. Wolfgang Schippke (
http://dc3mf.tripod.com/Index.htm). 
I then asked on BP who knew anything more about the islands. If my 
memory serves me well, Arif had some doubts regarding the accuracy of 
the map on that site (
http://www.425dxn.org/dc3mf/penon.html). But 
that was it. Now the maps on this site that you mention here are not 
very conclusive either - yes, the islets are very tiny - but there 
they are again! Do you or anyone else here know anything about them? 
Marcel: "(...)Another curiosity: the tiny sand line that joins the 
Peñón Vélez to the Morocco coast that forms perhaps the shorter 
border on the world was formed on 1934, after a great sea storm."
I thought someone else here mentioned it was the result of Moroccans 
building a road nearby. But it was mentioned as "the shortest 
international border in the world".
