How do I find the Vertical Datum of a Digital Terrain Model if its not given in the metadata?

Mapping Center Answer:

Guess? :-)  The fact is that you either have to find out what it is from the source or you have to compare it against some known data, just the same way you would if you did not know the horizontal datum.
