Which description matches a boundary monument with a tablet?

Which description matches a boundary monument with a tablet?

• A. A Boundary monument, Third-order or better elevation, with tablet.
• B. A Boundary monument, Third-order or better elevation, recoverable mark, no tablet.
• C. A Vertical control point with a tablet.
• D. A Principal Point on provisional edition maps.

Answer: (A)

The important idea is how survey markers are described to convey both what the object is and its level of precision. A boundary monument is a physical marker set to define a parcel line, and when the description says it is “with tablet,” that means a metal plate or inscribed tablet is attached to the monument to identify it. The phrase “third-order or better elevation” signals that the vertical position of the marker was measured with a high level of accuracy, meeting or exceeding third-order standards. So, describing a boundary monument as having a tablet and a third-order or better elevation exactly matches the situation of a well-documented boundary marker that carries an identifying tablet and has a precisely determined height. Other descriptions would refer to different things: a boundary marker without a tablet lacks the identifying plate, a vertical control point is about vertical positioning rather than boundary lines, and a principal point on provisional maps relates to mapping rather than an on-site marker.
