Kloppstert
The Kloppstert is a hill, roughly  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.

Geography 
The hill lies about  south of Sieber,  east of the Fissenkenkopf and  northwest of the Adlersberg.

Other hills of the same name lie in the Harz near Lerbach and near Badenhausen as well as in the Solling hills southwest of Dassel.
