Hail owls

Instead of reaching the surface of the earth at the Papenkaule volcano, which is about 300 meters away, the red-hot magma had found a new path in the underground karst cave system and emerged here at the Hagelskaule, from where it finally flowed further into the Kylltal.

The sputum products of the Hailskaule are invariably rust-brown in colour. It also differs particularly in the weight of the ejected products of the hagelskaule, the papenkaule scoriae are remarkably light, those of the hagelskaule more than twice as heavy. The olivine content of the Papenkaule is higher, the inclusions of the Hagelskaule show more quartz.kulturdb.de/einobjekt.php?id=30218
