The pond in front of the Salmenkangas delta is a kettle hole that formed at the end of the ice age when a large block of ice buried in the layers of sand and gravel melted. The southeastern ridge of the delta, on the pond side, has been eroded into a steep slope by flowing water. Nowadays there is a Lohikoski church and graveyard on the delta. There is a summer market and the memorial of Mark by the pond. Nearby you will also find a village shop, café, boat dock and school. The distance to the Lohikoski mill is about 1.5 km along Myllytie. The Saimaa Geopark sign is on the edge of the summer market.
