The small historic town of Monschau in the Eifel region
      The   Eifel   is   a   low   mountain   range   in   the   west   of   Germany,   with   the   volcanic   cone   “Hohe   Acht”   as   the   highest   elevation   of about   750m.   The   biggest   part   of   the   Eifel   is   of   volcanic   origin.   Volcanism   began   about   50   million   years   ago   and   continues   to this   day.   The   last   volcanic   eruption   happened   about   11,000   years   back.   Geologically   the   volcanism   is   still   active   with fumaroles   of   carbon   dioxide,   and   eruptions   are   still   possible.   On   walking-tours   we   can   see   volcanic   cones,   craters,   lava   flows and Maars (round volcanic craters caused by magmatic explosions).       Along   the   river   Moselle   we   can   see   one   of   the   famous   winegrowing   areas   of   Germany   with   vineyards   going   up   the   slopes. This scenery we wanted to see from bird’s eye view.
We chartered this small aircraft for our sightseeing flight We are flying above a sinuosity of river Moselle near the village of Bullay. Here we clearly can see the vineyards Now we are nearing the small town Cochem This bridge is crossing river Moselle at Cochem The village of Pommern comes into sight We are crossing the village of Pommern The Pulvermaar is about 25,000 years old, with a diameter of 700m and a depth of 70m The Schalkenmehrener Maar dates back 11,000 years. It is 20m deep with a diameter of 550m The Windsborn Crater Lake is a sunken volcanic crater, a so-called caldera The Mosbrucher Weiher is a silted up maar, now bogland, 11,000 years old and with a diameter of about 600m Now we are walking through the landscape of the Volcanic Eifel Here the red volcanic rock comes to light This is a vertical slope of red lava These lava flows are interesting study subjects for geologists A group of students of geology are analyzing this lava flow Wild shrubs are growing on the lava We are passing precipices of lava rock These „Lava Bombs“ have a diameter from fist-size to more than a meter „Lava Bombs“ of molten rock are thrown high up during volcanic eruptions
