Caspar quarry, Ettringer Bellerberg Mt. (Bellberg Mt.; Bellenberg Mt.; Billenberg Mt.; Boilenberg Mt.), Bellerberg volcano, Ettringen, Mayen, Eifel Mts, Rhineland-Palatinate, Germany

(Steinbruch Caspar, Ettringer Bellerberg (Bellberg; Bellenberg; Billenberg; Boilenberg), Bellerberg Vulkan, Ettringen, Mayen, Eifel, Rheinland-Pfalz, Deutschland)

Active quarry. A multitude of often very rare, but well-crystallised minerals occur in xenoliths and basaltic rock.
Access is strictly limited (it was for most of the last two decades also completely forbidden).
Located between Ettringer Bellerberg and Büden mountains.
