extinct volcano on the western side ofSangay National Park inEcuador , 170 km south ofQuito . Spaniards named it as such as it resembled a huge cathedral to them. The Inca called it Capac-Urcu, which means "King Mountain" inQuechua .Geology
The mountain consists of a large
stratovolcano ofPliocene -Pleistocene age with acaldera breached to the west. Inca legends report that the top of Altar collapsed after seven years of activity in about1460 , but the caldera is considered to be much older than this bygeologist s. Nine major peaks over Convert|5000|m|ft|-2 form ahorseshoe -shaped ridge about Convert|3|km|mi|1 across, surrounding a central basin that contains acrater lake at about Convert|4200|m|ft|-2|abbr=on|abbr=on, known as Laguna Collanes or Laguna Amarilla.Access and recreation
El Altar is perhaps the most technically demanding climb in Ecuador. December through February are the best months to attempt an ascent. Much more accessible is the hike to the lake within the caldera of the mountain. From Riobamba, one takes a bus for about an hour and then checks in at the ranger station, where nationals pay $2 and foreigners $10 to enter the Sangay park. About 4-5 hours of an extremely muddy trail (knee-high rubber boots are recommended) leaves one at the official refuge, which is sometimes inexplicably locked, although entry can sometimes be found through an open window. The refuge has many beds, a kitchen, and even hot water. To hike to the lake is another 2 hours from the refuge across a valley and up a steep hill.
