Dellen
Encyclopedia : D : DE : DEL : Dellen
Dellen is a lake system in the province of Hälsingland, Sweden. It consists of two lakes, Northern Dellen and Southern Dellen, appreciated among fly-fishermen for their distinct population of salmon trout.
Southern Dellen has a surface area of 52 km² and a water volume of 1226 million m³. Northern Dellen has an area of 82 km² and a water volume of 1,489 million m³.
The two lakes are only united by a short channel so it is disputed whether they should be counted as one or two lakes. If counted together, it would have a total area of 130 km², making it the 18th largest Swedish lake.
The vaguely circular lake system was formed by a meteor impact 89.0 ± 2.7 million years ago placing it in the Upper Cretaceous. The resulting impact crater measures about 19 kilometres in diameter. It has resulted in the area containing the rock Dellenite, which has become the provincial rock of the province.
Asteroid 7704 Dellen was named after it.
