Which of the following markers is typically placed flush with the ground?

The flush marker is specifically designed to be placed flush with the ground, providing a level surface that blends seamlessly with the surrounding landscape. This design is particularly important in certain cemetery settings where a clean, unobtrusive appearance is desired. The flush marker typically has a flat stone surface with minimal height above ground level, making it less prominent than other types of memorials, while still functioning as a grave marker.

Other choices represent different types of memorials or markers that do not sit level with the ground. For instance, horizontal tablets are raised above the ground, often with a noticeable thickness and height. Ledgers, which serve as larger grave markers, also extend above the ground and are typically wider. Lawn crypts are designed as burial spaces beneath the surface, usually requiring some form of above-ground monument or marker, which does not align with the definition of being flush with the ground.
