In 2001, shatter cones were found in Kuukkarinselkä making it the 6th known impact crater in Finland. The crater, usually referred as Suvasvesi North crater, is located in the center of Kuukkarinselkä and measures about 3.5 kilometres (2.2 mi) in diameter. Its age is estimated to be about 85 Ma[4] but the Earth Impact Database (EID) gives a broader span of less than 1000 Ma.[5]

Haapaselkä resembles the northern counterpart and it was also suspected to be an impact crater. It has recently been confirmed and is usually referred as Suvasvesi South crater.[1][2][6] It is similar in size, and the age of the crater is estimated to be older than 700 Ma (probably about 710–720 Ma) based on argon-argon dating of impact melt rocks found near the southeastern shore of Lake Haapaselkä[7] but EID gives it as around 250 Ma.[6]
