.

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.

About

Dennis J. Mouland formed WTC in 2010 to re-engage the profession with the high-quality seminars and advice for which he had become famous. He formerly owned Cadastral Consulting, Inc. which he was required to sell when he took employment with the Bureau of Land Management (2005). That successful business was sold to Wendy Lathrop, PLS, CFM, who continues to offer a very wide variety of speakers and subjects. In mid-2011 Dennis resigned from BLM to return to his preferred activity: teaching about this great profession. WTC is the new seminar source Dennis has created. Please explore this site.
