+Tacguy Posted December 2, 2002 Share Posted December 2, 2002 I saw the list that Jeremy made about old benchmarks, but only one was in Ca. and it appears to be suspect. Californnia does not have the history that some of the eastern states have so how can I look up older benchmarks in this state? Quote Link to comment
+rogbarn Posted December 2, 2002 Share Posted December 2, 2002 This is an interesting question, but I don't know how to do it. The NGS site allows a search by date but the from and to dates have to be within the same calendar year. Not very useful in this case. Does anyone else have any ideas? Quote Link to comment
survey tech Posted December 2, 2002 Share Posted December 2, 2002 Try searching a small radius centered on the oldest institution in a given community, typically a courthouse, church, school, etc. Also focus on old rail lines, as many long bench level runs followed these routes in the early days, and development has often bypassed them, so many of the oldest markers are along old railways or what remains of them. Where they have been turned into trails or greenways, however, the markers will usually be gone. Quote Link to comment
