Where are the bonfires in World of Warcraft:Cataclysm?

I would like to fulfill all the requirements for [The Flame Warden], but I don't know where are the exact locations of [The Fires of Azeroth] and [Desecration of the Horde]. I used http://www.wowhead.com/achievement=1034 and http://www.wowhead.com/achievement=1035 , but it seems that Blizzard has moved the locations of the bonfires and I was unable to find them. Does anyone know where they could be?
