This is Eldhraun. A volcanic crater from very far back. Very liquid lava was boiling in this pot pretty much for an eternity. This formed a very thin crater edge that is fully round and has a deep hole in the middle. The hike up towards it is lined with blue berry bushes and birches. We couldn't help but collect more berries than we wanted.
