Lake Summanen (Finnish: Summasjärvi, Summanen) is a medium-sized lake of Finland. It is located in Saarijärvi, in the region of Keski-Suomi. There is a Stone Age Museum in the island of Summassaari.
== The Summanen crater == The 12th impact crater identified in Finland is located at the center of the lake. The crater is 2.6 kilometers wide, ~200 meters deep, and mostly buried under later sediments. The age of the crater is not known. It formed before the Quaternary glaciation, but on the other hand after the host rock which formed in the Svecofennian orogeny 1910 million years ago. (Plado et al. assume the impact was Phanerozoic, but give no evidence to support this.)
