Maar volcano.

Outcrops of basaltic lapilli tuffs with different types of xenoliths - ultrabasic ones (dunite, lherzolite, pyroxenite, hornblendite), mica schist, metasomatite and carbonatite - in a small abandoned sandpit north of the road leading from Dreis to Hillesheim.

Located 500 m west of Dreis and about 8 km north of Daun.
