ILLAMPU,
or SORATA, a mountain of Bolivia, in the eastern Cordillera, overlooking Lake Titicaca, 50 miles north-north west of La Paz. It is about 21,500 feet in height, and is believed to be the highest moun tain of the Bolivian Andes, though this distinc tion is also claimed for Illimani (q.v.) ; it is probably exceeded by the Cerro de Huascan in Peru and by Aconcagua in Chile. Illampu is a magthficent mass, with three principal peaks, of which the most northern one which fre quently is called Illampu by itself, has never been scaled. Seen from Titicaca it is the grandest mountain in America. Consult Con way, Sir W. M.,
