Thanks. Now that you show me the first ones, i learned to seek these my self too. The black spot -balls are clearly recognizable in the satellite picture, and if oyu change to map and then to terrain you get this kind of view;
This helps to search similar places, and so I actually even found this; "Balls Valley"
Just few km south-east from there is an interesting valley Full of these dots. So many, that I have doubts if these are bushes. This place might not been even explored yet.
