More specifically defined by a tidal datum determined by observing long-term tide levels.

boundary monument- A material object placed on or near a boundary line to preserve and identify the location of the boundary line on the ground.  Where it is impracticable to establish a monument on or very close to boundary line, the position of the boundary line on the ground is preserved by reference marks.  The term monument is sometimes used to include both the mark on the boundary line and the reference marks.   See also monument [USPLS].
