Cerro El Muerto which receives much more tourism in comparison. Cerro El Muerto Cerro el Muerto (sometimes "El Muerto" fully translated as "The Dead One Hill"") is a mountain peak of South America and is part of the Andes mountain range. It is also known as the 16th of the largest mountain peaks in the Argentine-Chilean border at . The first successful climb was made in 1950. The peak does not receive many climbing attempts due to the difficulty of navigating there from the Argentinian side of the mountain. Also, the closest neighboring mountain is Ojos del Salado, South America's second highest peak
Ojos del Salado of fumaroles high on the mountain and recent-looking lava flows, albeit of uncertain age, also argues in favor of a categorization as "active." By these definitions, Ojos del Salado is the highest historically active volcano on Earth. If the older date is accepted, the title of "highest historically active volcano" might reside instead with the somewhat lower Llullaillaco volcano, which certainly has erupted in historic times (most recently in 1877) and is considered active. Salado's rock is predominantly potassium-rich dacite and rhyodacite. Its lavas are high in biotite, hornblende, plagioclase, and opaques, with lower levels of augite, quartz, and hypersthene.
