In the Antiplano, the tortured landscape shows all of the forces that can carve the land. Here you can see folding planes of mountain building, volcanic lava flows and the work of wind and water erosion. In this enlarged image of a small section of the Antiplano can be seen several good examples of the steep regular shape of volcanic cinder cones. The near perfect cone of a volcano. In the circle is the almost pure black shape of the lava flow and ash field of a very recent volcano.
Older examples lose the pure black to normal weathering.
This particular example seems to be only a few years old.
