    Ummm...not to be a party pooper, but there is a web site (USGS?) that lists 
    all USGS benchmark sites and their latest recorded
    positions along with any adjustments noted. 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.
