        Remains of Witness Tree near Grand Canyon, AZ

Witness Trees are the more antiquated term for bearing trees. These are specific trees noted and marked by the original General Land Office surveyors as they crossed the country laying out future homestead properties. A Witness Tree aids future surveyors in the accurate positioning of ancient monuments and other evidence of the first survey. They have withstood the test of time by providing survey location data for hundreds of years, in spite of development, mining, forestry, and other improvements made by civilization.

The existence of and measurement data for Witness (or Bearing) Trees is contained in the original field notes of the General Land Office.  Although often difficult to read or decipher, they contain important information for the re-establishment of property lines in their original locations. 

Modern-day surveyors are required to search for and utilize this data, even if their measurement capabilities are extremely more precise than those used to mark and locate the tree or other evidences.  Original Public Lands Survey System (PLSS) monuments and other marks, like these, control land locations in all 30 public domain states.  The PLSS was instituted by Congress in 1785 and continues to be the basis for land titles in those states.

* About our new logo.  The witness tree shown was drawn by a gentleman named Ted Drummond.  He was a 30 year employee for DOI and drew the current Interior seal (with the buffalo).  The tree drawing was first used in a Corner Restoration Circular in 1952, shortly after GLO became BLM.  He and others drew some great pictures of survey evidence and restoration processes.

                       May's advice from Dennis:

Honesty is the fundamental part of ethics.  You cannot be a dishonest slime-ball in your personal life and somehow change hats when you walk into the office.  You are who you are....and you can decide to be an honest ethical surveyor everyday.
