Tunupa is a dormant volcano in the Potosí Department of southwestern Bolivia. It stands on the northern side of the Salar de Uyuni at an elevation of 5,321 m (17,457 ft) on the Bolivian Altiplano. Tunupa was active in the Pleistocene, with most of the volcano constructed by lava flows that erupted between 1.36 and 1.56 million years ago. Later glaciers developed on the mountain. There is a cave with several mummies about half way up and an ancient village at the foot with a modest "salt hotel".
