PerryNH I think raising the level of an area of earth is an interesting solution to adding several feet of height to an AM antenna without running afoul of the radiating vertical ground lead.
My own mulch pile is not very large in diameter, but does raise the average terrain at one location by about four feet.
Possibly some landscape techniques could be applied by way of supporting block containments to raise a particular area to even greater heights while blending it into the overall skyline.
The objective, if attainable, would be to have the antenna looking at a downward angle toward the target area.
