Thanks!

You can interogate the site by giving it a lat/lon box and asking for a list of any benchmarks in it, so it may be possibly to simply locate a nearby benchmark and confirm the elevation and survey date. There will be notes about the map datum and vertical offset as well. I think someone from this list had originally given it to me, I can't seem to locate it right now.
