These amazing weathered rocks in the village of Fabedougou, near Banfora, in Burkina Faso, are nearly 2 billion years old sculpted into quirky dome like shapes by water and erosion. The domes are about fifty meters high and formed at a time when this area was occupied by an ocean. The site is both an excellent view and climbing spot.
