Amantani is another small island on Lake Titicaca. The people living here speak the Quechua language. About 4,000 people live in 10 communities on the nearly circular island. It has two mountain peaks, called Pachatata (Father Earth) and Pachamama (Mother Earth). Both peaks have ancient ruins on the top. The hillsides planted with wheat, potatoes, and vegetables. Most of the small fields are worked by hand. Long stone fences divide the fields, and cattle and sheep also graze on the hillsides.
