Hello Gail,

Not to get anyone's hopes up by the revision of the Subject line...but,
unfortunately...I am not aware that there is a can refernce available
online...only the old hard copies (like Jim Rock 1990).  
OH!... almost forgot about the IMACS site...with ALL sorts of info on
various artifact types (including PREhistoric).  But, the BLM should
have this web link made available to their volunteers. ?

Here's the IMACS "Tin Can" page (but, are they all tin?)
http://www.anthro.utah.edu/IMACs/471-TinCans.pdf
And the figures that go with it:

And their Home page with the list of other pages (down left side):
