Beschreibung:Inca legends report that the top of Altar collapsed after seven years of activity in about 1460, but the caldera is considered to be much older than this by geologists. 9 major peaks over 5,000 metres (16,400 ft) form a horseshoe-shaped ridge about 3 km across, surrounding a central basin that contains a crater lake at about 4,200 m (13,800 ft), known as Laguna Collanes or Laguna Amarilla.Sources: - wikipedia - Hall, Minard L.
