A golf course distance marker suited for anchoring in grassy turf includes a cap, an integral hole stop shoulder, a circumferential blade depending from the outside periphery of the shoulder, and a central anchor stem. Distance data is indicated preferably on one or more, removable, colored coded tabs or colored strips sandwiched between the marker cap and a transparent, removable tabs which snap into and anchor within a pair of slots through the top surface of the cap. The circumferential blade extends downward around the periphery of the marker, so that rotation of the marker rotates the blade to cut into the grassy turf at the location being marked. The anchor stem extends coaxially downward below the circumferential blade to insure axial rotation of the marker as the blade cuts into the turf. Preferably the anchor stem of the invented marker includes an extending helical thread winding around its tip such that rotation of the marker in one direction forces or drives the blade into the turf, while rotation in the opposite direction loosens and lifts the marker from the turf. The hole stop shoulder comprising an inwardly extending annular shoulder at the base of the circumferential blade establishes the depth to which circumferential blade cuts into the turf. The cap includes receptacles for cooperating with a turning tool providing mechanical advantage for twisting the marker about its central anchor stem. A groundskeeper uses invented marker to cut its own hole and then seats it in the hole with the top surface of its cap flush with the surrounding turf. A turf plug recovered from seating the marker at a new location is used to fill the vacated marker hole.
