Coords To The Elemental "dungeons"

Ive been searching for a while but searching the lost lost canyon is a pain. ive been looking for all the elemental "dungeons" in there but I dont actually know exactly how many there are. Ive only been able to pin point fire and water, but I remember seeing a earth and people talk about the air.

Anyone have coords to all of these?

 

I don't have the exact cords right now but I know the earth one is really close to the Bantisu temple.

 

I don't have the coords to the earth one, but I know how to get to it...
Find the start NPC to The Lost. Between the path to Bantisu and the path to the huge statue behind Kandon-Beda, there is another path. Take that until you see a hill on the right side. There will be gnome mobs there, go into the cave :)
It's also right next to one of the T4 chests you showed in a video

 

Earth d is near temple
You have to Find gnome cave

 

Water is close to the flying house on the Rock. If you climb up the waterfall you have to solve a riddle (Finding the right entrance) and then kill some mob which drops a water Aura or however you call it...
