Árbol de Piedra ("stone tree") is an isolated rock formation in the Eduardo Avaroa Andean Fauna National Reserve of Sur Lípez Province, Bolivia.
Much photographed, it projects out of the altiplano sand dunes of Siloli in the Potosí Department, about 18 kilometres (11 mi) north of Laguna Colorada. Known as the "Stone Tree," it is shaped like a stunted tree, and is formed into a thin rock because of strong winds and the material is sand stone.
