(Kalkberg, Lüneburg, Niedersachsen, Deutschland)
A small hill in the western suburb of Lüneburg, formerly the site of a gypsum quarry famous among collectors in the 19th Century for its boracite crystals (type locality). Now a nature conservation park (digging prohibited!). Geologically the hill is a saltdome caprock, diapirically extruded so that it rises above the otherwise flat plains. Uplift continues at a rate of at least a millimeter per year.
