What type of grave marker is set parallel with the surrounding terrain?

A flush marker is a type of grave marker that is installed level with or parallel to the surrounding terrain. This design not only allows for a smooth and unobtrusive appearance but also helps blend the marker into the landscape of the cemetery. The flush marker is often made of materials like granite or bronze and is placed directly onto the ground, making it clear and accessible for visitors while minimizing interference with maintenance activities such as mowing.

In contrast, other types of markers, such as ledger, horizontal tablet, and lawn crypts, generally stand above ground level. Ledger markers are large flat stones that cover the entire grave, typically protruding at least slightly from the ground. Horizontal tablets are raised above the ground, making them distinctively visible, and lawn crypts refer to an above-ground burial space designed to resemble a small monument or structure. Each of these alternatives deviates from the flush marker's level positioning relative to the terrain.
