The vent of  Fliegerdenkmal has a structure maar type.

Instead of being filled by a lake as are the maars in the Eifel, it was filled by lava flows, partly eroded, as the structure bordering originally.

One kilometer southwest of Wasserkuppe, the Pferdskopf leaves no guess its origin ... a deposition analysis revealed a highly explosive past: an explosive eruption produced a ring that has been eroded. From the trachyte dome extruded at the end of eruption is only one small part of which is the current top of Pferdskopf (875 m). Remains of a lava flow in blocks are also visible.
