Due to its location below the Zugspitze and the clear, green-tinted water, the lake is considered one of the most beautiful lakes in the
Bavarian Alps. It was formed when the Isar Loisach glacier withdrew at the end of the
Würm glaciation and left a depression that filled with water. Between 1700 BCE and 1400 BCE, a landslide with an area of 13 square kilometers and a volume of 350 million cubic meters crossed the central and eastern part of the lake. The estimated energy released during this landslide event with an average fall height of 1400 meters corresponds to approximately 2.9 megatons of TNT (approximately 220 Hiroshima bombs). This resulted in a major modification of the morphological shape of the Eibsee valley. The shape of today's lake with its 29 hollows and 8 islands was created. It is one of the rare cases in which islands and shallows of a lake are geologically much younger than the lake basin itself. Around 8 submarine crests have depths of less than 3 meters. The only noteworthy inflows above ground are the Kotbach, which flows into the northwest tip of the lake, and the Weiterbach in the south. The lake is a 'blind lake', since there is no above-ground drain and water can only drain off or seep away underground, due to the location of the pool. It is believed that the source area of the Kreppbach (locality Rohrlaine), which is located almost 2 km northeast, is fed underground by Eibsee waters. == Name ==
