Basaltic Dike at Rodderberg Volcano (Bonn, Germany) - Places of Geologic Significance on Waymarking.com

Rodderberg Volcano
About 500.000 years ago, hot magma rose from deeper regions. When it reached ground water close to surface, it came to an immense phreatic eruption which formed the maar crater, nowadays about 50 m deep. The crater is approx. 800 m in diameter and is still well visible from the aerial perspective. About 300,000 years later the Rodderberg awoke once more to life. This time with a series of slag eruptions. An especially well visible report of one of these later eruptions is a column full with lava, that forced its way into slag deposits in the northern pit. The slag was degraded and the basaltic dike persisted by reason of its bigger hardness. It can still be admired in this place.
