Which type of corner has its original monumentation intact?

1. Obliterated corner

2. Lost corner

3. Existent corner

4. Virtual corner

The correct answer is: Existent corner

An existent corner is defined as a corner point that still has its original monumentation intact. This means that the physical marker or monument, such as a metal nail, stone, or other types of boundary markers, is still present at the designated location, clearly indicating where the corner lies. In surveying, the integrity of monumentation is critical for accurate property delineation, as it serves as a reliable reference for land boundaries. The existence of original markers allows for straightforward verification of property lines and is essential for maintaining the history of land surveying. On the other hand, obliterated corners have experienced some form of disturbance or removal, making them unreliable; lost corners are those whose original markers are entirely missing and cannot be located; and virtual corners exist through methods of reconstruction based on evidence or measurements taken from other known points rather than the original physical markers. Each of these conditions presents challenges in surveying processes, while an existent corner provides clarity and assurance in property demarcation.
