Which of the following is described as a visible marker used to denote a deed description?

A visible marker used to denote a deed description is known as a monument. Monuments serve as physical indicators in the real estate landscape that provide reference points for property boundaries, ensuring there is a clear understanding of the extent and limits of a parcel of land. These markers can be natural landmarks, such as trees or rivers, or artificial elements like concrete markers or metal pins placed by surveyors.

While boundary lines and property lines refer to the defined edges of a parcel or property, they do not inherently imply a physical marker. Boundary lines establish the perimeter of a property in legal terms, but without a physical representation, they remain abstract. Survey points are markers established during a survey, typically for measurement purposes, but may not always be visible in the context of everyday property identifiers. Monuments, therefore, stand out as the correct answer due to their dual role as both a physical and legal reference for property boundaries.
