Äksi Kalevi keskmise poja lingukivi

Near the southern end of Lake Saadjärv, between Äksi and Kukulinna, lies the boulder counted as the sling stone of Kalev's middle son. Local tradition places three great stones around the lake, thrown by the brothers when they competed by throwing to decide who would inherit their father's realm. Old tales add that Kalevipoeg once waded straight through Saadjärv with hundreds of sawn planks on his back, and the water came up only to the laces of his bast shoes. When he also waded through Lake Ilmjärv, the mud he shook from his shoes became the high Kolsi hill.
