Is an "Obliterated Corner" considered lost or existent?

An "Obliterated Corner" refers to a survey corner that has been destroyed or significantly altered to the point where the original marking cannot be directly identified. However, the precise location of this corner may still be recoverable through evidence from surrounding property markers, recorded surveys, or historical data.

The reason this type of corner is considered existent is that, while the physical marker is no longer present, the location it represented can often be determined. Surveyors use various techniques, including referencing other known corners or conducting mathematical calculations based on existing surveys, to find the corner’s coordinates.

While a lost corner would suggest that there is no means of recovery or reference available, an obliterated corner still provides the potential for reestablishment based on the evidence that exists. Thus, it is considered existent as the surrounding information can lead to discovering its previous location.
