A ground anchoring device includes a sharpened central shaft portion along the axis of a helical or spiral portion. The helical portion winds around the central shaft portion and the central shaft portion extends some distance beyond the lower end of the spiral portion to facilitate an initial insertion of the device into the ground. Once the central shaft portion has been pushed or driven into the ground until the lower end of the spiral contacts the ground, the anchor is then twisted to screw the spiral portion into the ground as far as desired. The twisting is facilitated by the fact that the central shaft holds the angle of insertion fixed.
