Abstract: A ground marker is provided for displaying distance and advertising information on a golf course. The marker has a body that is dimensioned to fit entirely within a predetermined size hole defined in the ground. The body has a top portion and a base that are generally cylindrical and coaxial. The top portion has a transparent top face that is positioned generally flush with the ground surface, and a protruding lip that is dimensioned to bear against the side of the hole. The top face is formed from a clear plastic filler positioned over a card containing markings. The filler has a hardness comparable to the hardness of a grassy fairway. The lip of the marker has a bottom surface that abuts with a tool for permitting easy removal of the marker from the hole. A method of marking distances on a golf course is provided by arranging a plurality of markers at spaced intervals along concentric radii measured from the golf green.
