An impact resistant marker having a marker base which is adapted to be secured to the ground or other substructure. The marker base has an upward protruding mandrel to which an elastomeric sleeve is mounted at one end, and at the other end to a substantially rigid, elastomeric mounting core. A pair of retaining lugs are integrally formed and protrude laterally outward from the sides of the mounting core. A replaceable tubular marker post having an elongate central opening is provided with a pair of apertures for receiving the retaining lugs when the mounting core is inserted into the central opening of the marker post. The retaining lugs prevent the tubular marker post from being pulled from the mounting core. The flexible element restores the marker post to its original position after it is struck.
