Hillesheim (Graulai)

Graulai near Hillesheim resides in the western Vulcan Eifel and is a great quarry for zeolites, and gladly the management gives permission to visit the site. I went there a few times together with a friend from Köln, and he showed me around. A lot of my finds are not photographed yet, so expect more to be added in due time. Usually one combines a visit to Graulai with one of the other locations nearby or even in the eastern Eifel, still relatively closeby (seen from NL).
