What characterizes a lost corner?

A lost corner is characterized by its inability to be determined in its exact location due to a lack of sufficient evidence or markers. This situation typically arises when original boundary markers are missing, destroyed, or otherwise cannot be located, making it impossible to pinpoint the corner's position with precision. In land surveying, lost corners necessitate the use of various methods and historical data to attempt to reconstruct an approximate location, often relying on past records, measurements, and other credible sources of information.

The other options do not accurately describe a lost corner. A corner that can be accurately determined would not be considered lost, as the defining characteristic of a lost corner is uncertainty about its location. An easily visible and identifiable corner clearly contradicts the concept of being lost, and a corner that has been vandalized may be evident but is still potentially identifiable, distinguishing it from a lost corner situation where no evidence remains at all.
