Funtensee
Extremely low air temperatures possible
The Funtensee is a karstic lake in the mountain massif of the stone sea in Berchtesgaden National Park and is situated at an altitude of 1601 m above sea level. NHN. About national fame, the lake gained through management -related cold records, which are not representative but for the wider environment.
Etymology
The origin of the Seenamens is debatable. For the determination of word roots Fontana ("Source " ) or sparks were proposed ( " Trout "). In ancient sources to find the spelling Fundensee.
Description
The Funtensee lies in a valley, covered about 2.5 hectares ( 3.4 acres officially be specified) and its shoreline is about 780 meters long. He is at the lowest point 5.5 meters and an average of 2.50 meters deep. The water catchment area comprises about 10 km ². Is fed primarily by the Funtensee aboveground inflows as the chair digging ( from the southeast, about 1600 m long) and the Renner digging ( from the west, about 900 m long).
The lake has no surface or otherwise visible outlets. On the eastern shore, however, is on the Devil's Mill, a verstürzten Ponor to hear a gurgling sound from the underground stream of water over behind a rock wall. From there the water reached within eleven hours the Koenigssee.
Formation
The valley in which the Funtensee is, was created over a long period by karst erosion processes and subsequent glacial reshaping. Geomorphological seen the terrain is a Uvala. Sinkholes formed by corrosion ( lime solution ) were dug even deeper by an up to 350 m thick glacier during the last ice age. After melting of the glaciers left moraine, the abdichtete the drains in the underground of the lake.
History
The use of Funtensee - area summer farming is already occupied in 1385. 1850 Funtenseealm was bumped with 185 cattle which summered was abandoned in the 1960s.
By the lake from time to time, the border between Bavaria and Salzburg. This was before 1810 and from 1816 to 1818 the case, in the meantime, the Duchy of Salzburg was transferred completely to the Kingdom of Bavaria.
A little above the lake lies the Kärlingerhaus, a large, during the summer season farmed mountain hut, the winter room is open all year.
Climate
The local climate on Funtensee occupies a special position. On 24 December 2001, a station of the company Meteo Media registered a temperature of -45.9 ° C. On the same day the lower Funtensee station of the DWD has a temperature of -44.0 ° C registered. The lowest temperature for the DWD Germany there is -37.8 ° C ( on 12 February 1929 in Hull / Wolnzach ) to.
The cold extremes explained by the topographic location of the lake, which is encompassed about by mountains and lies at the bottom of a basin. In winter, the rays of the setting sun fall here hardly ever to the bottom of the mountain boiler. On clear nights, the residual heat radiates. As the cold air from the sink can not drain, a pool of cold air forms.
The forest ends at the surrounding mountains about 100 m above the valley, the lake shore and the lower basin are completely free of trees. However, this inverted tree limit is apparently not a consequence of the cold air lake, but is attributed to the former use as a mountain farm.
