The Purico complex covers a area of about 20 x 30 square kilometres. It is located in the south of the Licancabur and Juriques volcanoes.
It consist of the Cerros de Macon (5'130 m) and Cerro Toco (5'604 m) volcanoes, several cinder cones and lava domes (Cerro Negro 5'016 m, Cerro Agua Amarga 5'058 m, Cerro Áspero 5'262 m, Cerro Chajnantor 5'639 m, Cerro El Chascón 5'703 m, Cerro Purico 5'375 m and Cerro Putas 5'462 m).
The area is home of the Llano de Chajnantor Observatory.
The illustration shows a view towards the Cerro Toco (5'604 m).
The Cerro Toco forms the north-eastern part of the Purico complex. From this point of view the Licancabur volcano is more at the left and the Juriques volcano behind the Cerro Toco. Between the Cerro Toco and Juriques volcano there is the Hito Cajon border point of the road which crosses the Atacama desert and connecting San Perdo de Atacama in Chile with Uyuni at the Salar de Uyuni in Bolivia.
