Laguna Colorada is an ignimbrite shield of the Altiplano-Puna volcanic complex at an altitude of 5,000 metres (16,000 ft) in Bolivia. Laguna Colorada is a c. 40 kilometres (25 mi) wide ignimbrite shield that was formerly also known as Panizos (not to be confused with Cerro Panizos. The shield is not clearly associated with a caldera but appears to contain a sag structure. The ignimbrite field is bordered by the Laguna Colorada to the west, Cerro Torque in the north and to the east; Laguna Colorada is also the origin of the name of the shield. Likewise, the "Tatio formation" at El Tatio originates from eruptions at Laguna Colorada; the 700,000 years old Tatio ignimbrite however is considered to be separate. An older ignimbrite was erupted 2.21±0.05 million years ago.
