Kaihunharju is a sharp-featured esker ridge surrounded by waters. It was deposited in a subglacial tunnel stream and crack between ice masses around 11,400-11,300 years ago. The Kaihunharju area is situated in a built-up area and is home to the marked network of paths called the Kaihu trail. There are connections to the Urpola nature centre (Saimaa Geopark visitor centre) and also to the Pursiala pothole. The Kaihu trail is signposted by Saimaa Geopark signs.
The Mikkeli area emerged from underneath the melting continental ice sheet around 11,300 years ago – at that time, the area was dominated by the Yoldia Sea shore, which reached almost 110 meters above sea level (msl). The summit plains of the esker delta to the southern area of Kaihunharju which formed at around the same time is nowadays around 106msl. As the ice sheet receded from the area, the earth’s crust began to undergo uplift, and approximately 10,700 years ago Saimaa underwent isolation in the Mikkeli area and formed an independent lake from its predecessor, the Ancylus lake.
