Sulkava drumlin terrain and Amadeus stone

The type of stone used for the Soutajapatsas monument stone at the Sulkava market square is mica gneiss, or more precisely garnet-cordierite mica gneiss, typical to the Saimaa area. Stone is multicoloured and richly hued: dark biotites and plagioclase crystals form a base intersected by light quartz and feldspar dikes. Stone is also dotted by grains of dark red garnet and blue-grey cordierite. The stone quarried from the local surroundings and used in building is known as Amadeus.

Experience the drumlin terrain of the Rowing municipality

The Sulkava market square and its statue of a rower are located in drumlin terrain. Drumlins were created as the glacial flow of the continental ice sheet modified material below it and laid material behind rocky hills into long ridges. The drumlins are part of the expansive Pieksämäki drumlin field, which formed in the central part of the Finnish Lake District ice lobe. The thickness of the till on the drumlins can exceed 10 metres. Drumlins are best seen on maps as a northwest-southeast orientation of the terrain.

There is a Saimaa Geopark sign on the edge of the market square.
