A turbine airfoil usable in a turbine engine and having at least one cooling system. At least a portion of the cooling system may be positioned in an endwall attached to the turbine airfoil. The endwall may include an endwall horseshoe cooling slot positioned in the first endwall proximate to the leading edge of the airfoil such that one end terminates proximate to the pressure side of the generally elongated hollow airfoil and a second end terminates proximate to the suction side of the generally elongated hollow airfoil. The endwall horseshoe cooling slot may include a plurality of film cooling holes angled to create a film cooling layer to reduce airfoil and endwall temperatures at the intersection between the leading edge of the airfoil and the endwall.
