Pistohiekka is a delta formation that accumulated along a 150km long fragmented stretch of esker. The area emerged from underneath the continental ice sheet during the time when local ice lake stage in the Lietvesi area changed into the Yoldia Sea stage around 11,400 years ago. As the water levels fell, the Pistohiekka and Pistohiekankangas delta formation was washed away and levelled.
Pistohiekka forms a shore feature site with an erosion bank measuring around 700m long and 3-4m tall. It also features ancient shorelines (at a Greater Saimaa stage height of 87msl) and rocky outcrops. Late Stone-Age dwelling sites where there have been archaeological findings are located in the ancient beach ridges.
There are several Saimaa Geopark sites in the vicinity of the Pistohiekka beach, including the Lietvesi scenic road and the Loketononkalo gorge, whose signs describe the geology of the area. Contents of the signs: Loketononkalo (pdf) and Lietvesi (pdf)
