Hatun Pastu (Quechua hatun big, pastu grass (a borrowing from Spanish pasto)[3] [4] also spelled Jatun Pasto) is a mountain in the Andes of Peru, about 5170m (16,960feet) high. It is located in the Puno Region, Lampa Province, on the border of the districts Palca and Paratía, southeast of the mountain Qillqa and north of Waykira.
An intermittent stream named Hatun Pastu originates north of the mountain. It is a tributary of the river Wila Wila (Vila Vila) whose waters flow to Lake Titicaca.[5]
