Url Crevasse (Japanese: ウルの裂け目, Uru no sakeme) is a location in Xenoblade Chronicles. It is a somewhat hidden location on the upper level of Valak Mountain. It is south of the Hollow Bone. The path to the crevasse is on the same altitude (i.e., do not descend into the Chilkin Lair) as the landmark. The path is somewhat blocked by a large crystal. The North Star Gusion lives here at night, during snow.
