Preaching the Kingdom on the Altiplano in Peru.
When they arrived on the Altiplano, they discovered a strange new world.
The taxi from El Alto international airport soon left the high,
flat Altiplano and dropped down towards La Paz, nestled in the canyon below.
Also in this region are the Altiplano and the Salar de Uyuni,
which is the largest salt flat in the world and an important source of lithium.
The sierra(highlands) is the region of the Andes; it includes the Altiplano plateau as well as the highest peak of the country,
the 6,768 m(22,205 ft) Huascarán.
Since the lake is located on the lower point of Altiplano, the waters of the higher plateau find their way into the lake
and little water drains out.
The research team tested this argument with samples from 16 countries, including the Negev desert in Israel,
the woodlands of New South Wales in Australia, the Altiplano of Peru, and the Pampas lowlands of Argentina.
