A utility locator which is positioned on the surface, but which is capable of providing extensive information concerning the character and location of utility facilities, or other similar types of subsurface structures. More particularly, the present invention is capable of providing information at the surface concerning the type of facility located below ground, the depth at which it is buried, its precise location, and its drift or direction of travel. In one embodiment, the utility locator comprises a multiple piece assembly. The manner in which the pieces are assembled and the types of pieces used provide the desired information. In particular, a round center piece may be used which has inscribed on its surface an indication concerning the type of structure marked. A second piece contains a mark on its surface. This mark is positioned with respect to a third piece such that the drift of the underground line is identified. This is accomplished by inscribing on the surface of the third piece the points of the compass. Depth is also indicated in a manner similar to that in which drift is indicated. In one embodiment, the third piece also includes a series of depth indications around its circumference. A fourth piece is then provided whcih also contains a mark. The mark is aligned with the number which corresponds to the depth of the subsurface facility (such as in feet or meters).
