06/21/12 - Believe it or not, there are a series of platforms to your right, seen only through the Lens of Truth. After you mount the first platform, continue to walk until you see a gap between you and the next platform. If you look down, you'll see an ice covered eye-switch. Shoot the ice covered eye-switch with a Fire Arrow, and the icy platforms will appear opposite you and the Beamos ledge. Hope this helps...good luck.
