The blue circles indicate "rocks" all around that area. This is a perfect example of where community edits can be great. Anyone can make a note saying exactly what you just said about that spot. All community edits are moderated, so they will be noticed. Additional, you can do just what you did here. Let us know on the forum or via email. This location has been noted and passed up to be looked at. Thank you for that. Moving forward, TZMaps will be more rapidly updated as they do not have to wait to release and entire region. Small sectors can be updated.
