Oops,

It was brought to my attention that a reference I posted in my response
to Myth Busting listed the wrong year.  It should have read Dunham and
Franzen 1997 (not 1999) with the complete reference as follows:

Dunham, S. and J. Franzen
1997  Bottles and Berms:  Test Excavations at Four Pine Era Lumber
Camps in Michigan's Upper Peninsula.  The Michigan Archaeologist 43
(2/3):127-152.
