LiDAR will detect a metallic object if it is above ground, it shows as a bright spot (a good reflection), easily picked out. I stress LiDAR because LiDAR would give me a picture of the ground. I would then be able to see where the bulldozer featured in 'my' quest had been working.... in order to assess what changes had been made to the uppermost 'crust' of the earth.

Surely if an idiot BD driver buried it, with LiDAR and the results of a large machine working in the area, I would be able to see changes to the surface of the hill, changes to the natural flow, if you like,

Obviously, if I had known about LiDAR and had it been available in 1994, I would have considered it. Hindsight is a good thing, when you can afford it,
