I'm in Menlo Park. The USGS has a big office complex here. That includes a bench mark just outside the front door of the main public building (map sales, talks, bureaucrats, ...). There may be a better one out near the flagpole. (It's out of the shadow/multipath of the building.) I'd expect there would be an on-line database of that sort of thing. Anybody know a good URL? ---------- Google blundered into this, but I haven't checked much: http://www.waymarking.com/default.aspx They have lots of records that aren't interesting but also a category of "US Benchmarks" that may be an interesting subset. While hiking, I've seen benchmarks by CA Highways (I think) so "USGS" may be overly restrictive. -- These are my opinions, not necessarily my employer's.
