The philosophers Kamlah and Lorenzen complained that our actions often carry with them the "heavy price" of unpleasant and unforeseen side effects. It may be the simplest of things. This is part of a long dry stone wall (top right in the photo) that was built with Khoisan slave labour in the Suurveld, perhaps two-hundred years ago. By now, the wall has torn part of the mountainside apart, and is itself about to tumble into the dongas it has made. OBSERVATION: One sees the damage on Google Maps, co-ordinates -33.894809 24.254699. However, it doesn't look as impressive from a satellite as it does on the ground.
