Häränsilmä kettle pond

Show map

Häränsilmä is a beautiful kettle pond in Lahti on the first Salpausselkä ridge, right next to the routes and trails of Lahti Sports Centre. The urban nature trail “Lehmusreitti”, which goes around the centre of Lahti, also runs by Häränsilmä. The kettle pond and its immediate surroundings form a nature protection area.


The Lahti Sports Centre area has several kettle holes, which give it its distinctive terrain, great for winter sports. The kettles were formed some 12 000 years ago, at the end of the last Ice Age, through the melting of enormous ice blocks that had split off from the continental ice sheet. These ice blocks were buried in the sand and gravel deposited by the glacial meltwaters. As the ice melted, the land around the blocks collapsed forming the pitted kettle landscape.

Sometimes the bottom of kettle is below the surface of the groundwater or perched groundwater, turning the kettles into kettle ponds. Perched groundwater is groundwater formed above the actual groundwater, on top of a water-impermeable layer. In the case of the Häränsilmä kettle pond, the perched groundwater has been dammed on top of a water-impermeable layer of till, and the pond lies about 20 meters above the groundwater surface.

The surface area of the Häränsilmä pond has originally been about one hectare, but as a result of natural overgrowth, the water surface has shrunk to one-fifth. The pond and its surroundings provide habitat for several plant and animal species.
