ABSTRACT:
An underground marking system for marking buried objects is constructed from synthetic, brightly colored materials, which provides redundant horizontal and vertical markers and the ability to trace back to the buried object. The system is economical and easily installed. In one embodiment, the system includes a base disposable adjacent to the object, a hollow member having a lower end attachable to the base. The upper end is disposable adjacent to the ground. A cord is disposed in the hollow member and extends from the lower end to the upper end of the hollow member. The system provides a way of easily locating the marker either above or immediately below the ground surface. The hollow member may include a calibrated marking system to identify the depth to either the base or the buried object from the point of discovery of the hollow member.
