What type of grave marker covers a grave completely and is set parallel to the ground?

The type of grave marker that covers a grave completely and is set parallel to the ground is a ledger. These markers are typically larger and cover the entire grave, distinguishing them from other types such as flush markers, which are low-profile stones that sit close to the ground but do not cover the grave entirely. Ledger markers often serve as both a headstone and footstone combined into one piece, making them a visually striking choice for memorialization. They are commonly used in cemeteries and provide a flat surface that can be engraved with the deceased's information and often decorative designs. This differentiates them from a mausoleum, which is a structure that houses the deceased above ground rather than marking a grave, and from general markers, which can vary widely in size and design but do not necessarily have the same full coverage as a ledger.
