Man, this place is so fucking lame. For a mountain full of gravestones, there really isn't anything interesting to do in it or anything interesting that happens with it storywise, other than the mandatory team magma/aqua event, and even that's really boring. They could've at least put some legendary pokemon in it or a special event for a rare pokemon, but the best you get is the Shadow Ball and some useless shitmon with a 2% encounter rate.
