Windsborn crater lake

The Windsborn crater lake is a water-filled volcanic crater in the Eifel , which is part of the Rhenish Slate Mountains . It is located near Bettenfeld in the Rhineland-Palatinate district of Bernkastel-Wittlich and belongs to the Mosenberg series crater group , which is named after 517  m above sea level. NHN high Mosenberg received.

Geographical location

The Windsborn crater lake is located in the southwestern Vulkaneifel and in the Vulkaneifel Nature Park . It is located 1.2 km east of the village church of Bettenfeld on the north-northwest part of the Mosenberg, a little below 470  m . The crater lake is the third crater of the Mosenberg series crater from the south and extends in the Mosenberg and Horngraben series crater nature reserve , which also includes the Hinkelsmaar (sometimes also called Hinkelmaar ) in the fourth crater 330 m north-northeast of the Windsborn crater lake. Northwest to north past both craters in the valley of the Ellbach , a small tributary of the Kleine Kyll , the state road  16 leads past, which connects Bettenfeld and Manderscheid , which is 2.8 km east-northeast of the Windsborn crater lake and east of the Kleine Kyll .

The Windsborn crater lake is one of the rare real crater lakes north of the Alps . Sometimes it is misleadingly called the Windsbornmaar , although the two types of volcanic lakes have different origins: A maar is created when the blown funnel fills with water after a phreatomagmatic explosion . In contrast, a real crater lake forms either in a volcanic crater or in a caldera , as it results from the collapse of a magma chamber close to the surface . The latter variant applies, for example, to the Laacher See .

All volcanic craters in the nature reserve were created in a series of volcanic eruptions around 29,000 years ago. The Hinkelsmaar is also not a maar, but such a volcanic crater.

description

The circular Windsborn crater lake is completely surrounded by a 20 to 30 m high wall that slopes steeply down to the lake. The wall is made up of the red-brown ash and sweat slag ejected from the original volcano.

At a depth of only 170 cm, the lake has nutrient-poor water because it has no inflow or outflow. The vegetation in the Verlandungs zone of the lake - as Bogbean and Marsh Cinquefoil  - is under nature conservation . Due to the shallow water depth and the uniqueness of the biotope , fishing on the lake was abandoned, instead a fishing substitute water with a water depth of 120 cm was created between the Windsborn crater lake and the community of Bettenfeld.
