Glacial Crevice is a location in The Elder Scrolls V: Dawnguard. It is a sublocation of the Forgotten Vale, that is inhabited by Falmer villagers. It is a large cave system deep inside the canyon. There are multiple hidden chests or entrances underwater, so waterbreathing is recommended. There is a hidden underwater cave that connects the first section of the lake to another, farther section. There is a small basin between them that contains several dead Falmer floating underwater and a chest on top of some ice on the surface. If this path is followed, the Dragonborn will avoid any conflict, and can take this path all the way to the cave exit.
