Abstract
Abstract This is a positive sub-surface utility line and the like indicator especially useful for providing a sure indication of the location of a sub-surface conduit or structure. The indicator is positively connected to the sub-surface conduit or structure, preferably by means of a measurement tape or the like, which indicates the distance the sub-surface conduit or structure is from the indicator which is located on the surface. Other features of the indicator include a flag-pole combination unit for providing an elevated visual view of the indicator, a recessed, protected pouch for containing information relative to the sub-surface conduit or structure, and a visual, surface symbol providing rapid indication of the nature of the subsurface conduit or structure.
