Kasota limestone or simply, 'Kasota stone,' is a dolomitic limestone found in southern Minnesota. This sedimentary rock is part of the Oneota Dolostone Formation of southern Minnesota and is approximately 450 million years old (lower Ordovician Period). This particular limestone is rich in dolomite and magnesium, making it resistant to weathering, and it is thus widely used as a building material.

The posse passed, twelve horse; the leader’s face
Was worn as limestone on an ancient sill.”
