Fascinating aerial photographs of the arid west coast of South Africa by Cape Town-based photographer Dillon Marsh. The patterns look similar to the Nazca lines in Peru but these are not the designs of an ancient civilization or extraterrestrials rather these are fields ploughed by local sheep farmers who grow wheat and barley to feed their livestock. According to Marsh, the level ground and soft soil are the required ploughing conditions and bands of natural vegetation are left untouched in between the worked strips. This last step is to prevent the topsoil from being blown away by the summer winds if the rain doesn't fall. A average decrease in rainfall in the last half century means that many of these fields are no longer used anymore and are slowly returning to their natural state.
