Vuoksenniska is part of the First Salpausselkä, where the Vuoksi outlet channel broke through 5,700 years ago as a result of the Greater Saimaa flood. In the Imatra region, the First Salpausselkä is between 1-2 kilometres wide due to the long deposition time of 200 years, during which time the ice edge also had time to move. The network of paths in the Vuoksenniska school area lead hikers to a delta plain dotted with a few kettles in its southern parts. Typical features of end moraine ridges can also be seen along the path: on the ice-sheet side to the northwest, the sides of the ridges are long and gentle, while the southeastern sides are steep, often with lots of boulders. There are Saimaa Geopark signs in the parking areas of Vuoksenniska school area and along the geological forest trail, which provide information on the geology of the area e.g. deltas, marginal-moraine ridges, rock types and kettle holes.
