Tsingy de Bemaraha (Stone Forest) - Madagascar
The Tsingys are karstic plateaus in which groundwater has undercut the elevated uplands. Because of local conditions, the erosion is patterned vertically as well as horizontally. In several regions on western Madagascar, the superposition of vertical and horizontal erosion patterns has created dramatic “forests” of limestone needles. The species of flora and fauna are not to be found anywhere else in the world like the Decken’s Sifaka pictured above.
