ABSTRACT:
A utility location indicator apparatus for indicating the location and general direction of lie of an underground utility includes a marker being configured to extend upwardly from a utility pipe to indicate a location of the utility pipe under a ground surface. The marker is elongated to extend upwardly through the ground over the utility pipe. A plurality of incremental indicia is positioned on the marker and incrementally extending along a length of the marker. The incremental indicia is configured to indicate a depth of the ground positioned over the utility pipe to alert a user to the depth the user can dig before encountering the utility pipe. A saddle is integrally coupled to a first end of the marker. The saddle is configured to extend over a portion of a circumference of the utility pipe to maintain alignment of said marker with the utility pipe.
