Introduction

Boundary monuments serve as the physical evidence of property lines and are crucial elements in land surveying. Their proper identification and documentation are essential for establishing accurate property boundaries and resolving disputes.

Important Note

Always verify monuments against historical records and previous surveys. A single monument should never be relied upon in isolation - always look for supporting evidence.
