The caves where first discovered when Jack was chasing his father. When he got there, he saw his father's coffin, with no one inside. There were two bodies found in the cave, whom Locke called them Adam and Eve. There is fresh, running water at the caves, which caused some people to move there. There was a debate between the survivors whether to move there or stay at the beach. A few days after moving in, a cave-in happened, trapping Jack. Charlie was able to rescue him. The caves where abandoned after the hatch was opened. Claire was attacked by Ethan at the caves. Because of that, Shannon called the caves the "Rape Caves". The caves have been mentioned several times afterwards. Hurley said that Steve brought water from the caves everyday, and Juliet said the caves were near Ethan's drop off spot.
