Fissenkenkopf

The Kloppstert is a hill, roughly 553 metres (1,814 ft) high, in the southwestern Harz in Lower Saxony, Germany. In the topographical map printed in 1978 it can only be made out with difficulty that the third letter is an o and the penultimate one an r. However, a contour line runs over the letter r so that it looks like a p. In the digitalised 1:25,000 topographic map, the hill is wrongly named as the Klappstept.
