Lammassaari is a delta belonging to the First Salpausselkä’s ice-marginal formation and it began to accumulate around 12,300 years ago. Only a small piece of island to the south remains at the original height of the delta (approx. 101-102msl) – elsewhere waves at different stages of Saimaa’s development have washed away deposits and formed clearly distinct ancient shorelines. Two Stone-Age settlements have been found on the shores of the Greater Saimaa stage (approx. 80msl). Several kettles serve as remnants from the ice age, with the biggest being a rather large, steep-edged kettle pond. There are beautiful and representative gneiss vein boulders, along a path to the north of the island, and a sheltered rocky area at the northernmost point. Lammassaari has several Saimaa Geopark signposts and a comprehensive network of trails.
