Which type of corner is one where monumentation has been disturbed or destroyed?

1. Existent corner

2. Obliterated corner

3. Lost corner

4. Identified corner

The correct answer is: Obliterated corner

A corner where monumentation has been disturbed or destroyed is referred to as an obliterated corner. In surveying terminology, "obliterated" indicates that the physical markers or monuments that previously defined the corner have been damaged, moved, or completely removed, making it difficult to ascertain the exact location without reference to other established points or historical evidence. When dealing with obliterated corners, surveyors often rely on records, measurements from nearby established corners, and documentation that can help recreate the original positions. The distinction is important as it guides surveyors in determining the necessary steps to re-establish a proper boundary. In contrast, an existent corner refers to one where the original markers remain intact, a lost corner is one that cannot be located but was never disturbed or destroyed, and an identified corner is a corner that has been located and marked. Each term highlights different conditions related to the corner's monumentation and its accessibility for identification and use in boundary delineation.
