Eifel
The Eifel is a hilly region in Germany. It occupies parts of southwestern North Rhine-Westphalia and northwestern Rhineland-Palatinate.
The Eifel is bordered by the Moselle river in the south and the Rhine in the east. In the north it is continued by the hills of the High Venn[?] (Hohes Venn), in the west by the Ardennes. (Ardennes and Eifel are actually the same geological region.)
In the Tertiary the Eifel was a site of extensive volcanic activity. Some of the hills are volcanoes, which became extinct long ago. The lakes of the regions are former volcanic craters (maars[?]).
There are several distinct hill chains within the Eifel.
