The Große Kranichsee (Czech: Velké jeřábí jezero) is one of the most important raised bogs (Hochmoore) under nature conservation in the Ore Mountains of Central Europe.
Location
The raised bog is located at an elevation of 950 metres above sea level (NN) in a high forest clearing southwest of Carlsfeld. The border between Germany and the Czech Republic runs through the reserve. West of the Kranichsee is the "black pond" (Schwarzer Teich).
Name
The name of the bog is related to the Slavic word granica, which means border.
Significance
It is a watershed and krummholz bog that is drained to the northwest by the Große Pyra and to the southwest by the Rolava. To the east is the Kleiner Kranichsee, where the heart of the bog, unlike the Großer Kranichsee, lies on the German side of the border.
Climate
Carlsfeld is a small settlement nearby to Großer Kranichsee.
