“The Uros use bundles of dried totora reeds to make reed boats (balsas mats), and to make the islands themselves. The larger islands house about ten families, while smaller ones, only about thirty meters wide, house only two or three. The islets are made of totora reeds, which grow in the lake. The dense roots that the plants develop and interweave form a natural layer called Khili (about one to two meters thick) that support the islands.
