A method of identifying perimeter markings for lines on athletic fields involves locating two or more perimeter points on a line of an earthen athletic field comprising a ground surface; drilling a vertical hole in the earth in said points; placing a flexible elongated marking rope with a ground anchor on one end thereof longitudinally into each of the holes so that the ground anchor is in the lower end of the hole, and so that the upper portion of the rope extends from the hole above the ground surface. Loose material, such as loose dirt, is packed into the hole around the rope whereupon the upper portions of the ropes above the ground surface will serve as visible indicators of the location of the points. The rope is a plastic rope of polyethylene or the like which is six to eight inches long. It has a ground anchor on one end. The ground anchor is positioned in the lower end of the hole drilled in the earthen surface and serves to anchor the rope in the hole when loose dirt or the like is packed into the hole around the upwardly extending rope.
