largest island of Sollerön |

The Siljan is the seventh largest lake in Sweden . It is located in the Swedish province of Dalarna . The lake has an area of 290 km², a maximum depth of 134 meters and a water volume of approx. 8 km³. The river Österdalälven flows through it. Another tributary comes from the northern Orsasjön , which is fed by the Oreälven .
Geology and geography
The geology of the lake and its surroundings was shaped by the impact of an asteroid that occurred about 370 million years ago. The previously existing impact crater was filled with younger sediments , mainly limestone . Today's lake and the surrounding area are the result of repeated glaciations in the Ice Age . The glaciers excavated the more easily eroded rocks of the crater filling than those of the surrounding area. Therefore, the Siljan and a number of other small lakes clearly trace the outline of the eroded crater. With a diameter of 55 km, the Siljan structure is the largest visible impact structure in Europe ( see also: List of impact craters on earth ).
There are several islands in Siljan, of which the 7.5 km long and 4 km wide Sollerön is the largest. The towns of Leksand , Mora and Rättvik are located on the banks of the Siljan . At the turn of the century around 1900 there was lively sea traffic with steam boats . Nowadays there are excursion boats that take sightseeing tours from the above locations. Traditional rowing competitions with church boats (traditional boats for Sunday church visits) take place at the end of June / beginning of July on the lake.
