The forest is not particularly unusual at all except that the locale itself is strategic at least as a choke point for containing Transylvania. The drainage passes close by on its way to the Danube. Otherwise the evidence points to a possible Earth Entry for UFOs except that seems unlikely without a lake to act as a shroud. There also appears to be no notice of exceptional geomagnetic signatures either.
There is nothing else here. Someone will have to do remote sensing some day.
The interesting question is whether or not this phenomena signature is found elsewhere (it is) in similarly uninteresting terrain. Can it be discovered by global mapping?
