Xbox 360 Getting to the chest on Aslan's How

[Marvel]

Can anybody steer me in the right direction to get this done? I can see the chest, but I can't figure out how to get to it.

Hey Marvel! Which chest are you talking about? Can you give us a little more detail? i.e. since you can see it, can you describe the location of the chest? There are quite a few chests on Aslan's How.
