• the coupler upper end having a cylindrical outer surface sized to closely interfit within the delineator lower end inner surface;
• the coupler lower end having a square cross-section outer surface;
• the coupler transition portion in a medial location of the coupler between the upper and lower ends;
• the coupler transition portion including a plurality of abutment projections extending from an outer surface thereof;
• a mount adapted to be driven into the earth, the mount having a square cross-section inner surface sized to closely interfit about the coupler lower end outer surface;
• the delineator lower end interfitted with the coupler upper end, the coupler lower end interfitted with the mount, the abutment projections contacting an upper edge of the mount;
• an upper fastener extending through the coupler upper end and delineator lower end;
• and
• a lower fastener extending through the coupler lower end and the mount.
