A road at the Kallahti nature conservation area in Helsinki, Finland. The Kallahti area contains an esker and land area rising slowly from the sea (a large glacier in the ice age has pressed the earth, which is still slowly rising). The nature conservation area is part of European Natura 2000 nature conservation program. There are 40 nature conservation areas in the City of Helsinki.
