Guide How Do You Get To The Lazarus Pit For The Quest: Lizarus Pit?

I'm stuck at the part in the quest where you have to find the Lizarus Pit, but the thing is I went to the coords but I don't think that the pit is above ground. And I can't find anywhere to go underground that leads to those same coords? If someone could please help me i'm lv 75 mage named fall1357. If you find out how to do this please msg me either on the forums or ingame.
Thanks,
fall1357
