There are so many huge rocks in special shapes in of Sur Lípez Province, Bolivia. The force of water and wind cannot be underestimated, because Mother Nature is a great artist and can shape any surface into his own will. Similarly, Árbol de Piedra also called "stone tree" is an isolated rock formation in the Eduardo Avaroa Andean Fauna National Reserve of Sur Lípez Province. The Siloli Desert, one of the driest places in the world, features a rocky outcropping with one formation in particular getting all the attention. The much photographed, it projects out of the altiplano sand dunes of Siloli in the Potosí Department, about 18km north of Laguna Colorada.
Siloli Desert has been whittled down into the exclusive shape of stone trees over time by sand and 120km/h winds that whip across 4,000m high Bolivian Altiplano in the colder months. Much looking like wind, sand, and water can sculpt out of the earth! This particular Bolivian reserve and arid, stark desert horizon coupled with strange rock formations strike a strong resemblance to the famous surrealist’s work. Moreover, the base of the rock has been weathered away by wind and time, while the top remained intact.
The seemingly incredible structure stands about 23 feet tall and casts its shadow even longer across the flat sandy desert. The "Stone Tree," shaped like a stunted tree about 7 m high, particularly the thin stem, are due to strong winds carrying sand and eroding the soft sandstone. This is Bolivia most famous natural places look like the head of dinosaur in the middle of arid desert which is unbelievable and especially interesting to see how the colors changing during one hour that you’d have been there. The more attraction adjacent to Árbol de Piedra are the salt flats portion, incredible scenery, Red lagoons, green lagoons, white lagoons, volcanoes, beautiful rock formations, hot springs, geothermal geyser fields and colorful, rainbow mountain ranges.
