Surveying the Ruins

I have to get over to the Ruins of Farahlon to start my excavations! The problem is that the place has been infested by demons!$B$BMaybe you could do some preliminary work for me?$B$BThere are three locations within the ruins to the northeast where I want you to place surveying markers. Each is near a draenei banner.$B$BReturn to me when you've managed to place all three markers.
