I am in the Depleted Ore Mines in The Orobas Fjords. Am in the room with the ledges that you jump on and they continue to go higher. Have made it to the top. Pulled the lever and it shows two extra ledges. The disappear in a hurry. Is there some trick to reaching them or do I just have to be really fast getting to them? Also there are three pedestals in the Depleted Mine that do nothing when I use them. Are the ledges and the pedestals related? I have killed everything in the mine. Thanks for your help. I am not one to give up and those ledges are making me nuts!
