Barta is under the skull of the Gerudo Great Skeleton, the Leviathan Bones in southwest Gerudo Desert. The quickest way to get here is to fast travel to the Hawa Koth Shrine, but be sure to select appropriate armor for either heat or cold depending on the time of day. Once you find Barta, give her the Hearty Durian.
