The hazard and boundary marker comprises a cylinder housing placed vertically beneath the ground or a playing, walking, or driving surface, and having an upper opening at or slightly above the ground or surface level. Said cylinder housing having an enlarged removable cylinder housing cap with a diameter greater than the cylinder housing attached to its upper opening. A retractable hazard and boundary marker rod is inserted through a hole in the center of the cylinder housing cap into the cylinder housing, allowing the rod to be lowered into the cylinder housing.
