[Possible Spoiler] New cave location

[seb3sec]

If you look east from the west coast you may see a little hole in the map. It's located near a lake (62.7 lat, 37.2 long). Since all other caves look the same way from the distance this might be a new cave. It is covered by a rock which can't be destroyed.
