What defines flush grave markers?

Flush grave markers are specifically designed to be level with the ground and set even with the surrounding terrain. This design allows them to blend seamlessly into the landscape, which can be aesthetically pleasing as it does not disrupt the natural look of a cemetery. The flush design can also make maintenance easier, as it eliminates the risk of tripping hazards that can be posed by elevated markers.

While options naming materials, shapes, and sizes may describe other types of markers or gravestones, they do not accurately capture the defining characteristic of flush grave markers, which is their level positioning in relation to the ground.
