Dear Folks,
 
I am working on a trampling experiment involving kaolin pipes.  I need some
assistance tracking down a reference to a similar experiment done by someone
named JUSTICE.  It is mentioned in a citation to the following item:
 
Pyszczyk, Heinz
 
1984  Site occupation length as a factor in artifact assemblage variability
      and frequency.  In Archaeology in Alberta, 1983, compiled by D. Burley
      pp. 60-76.  ARCHAEOLOGICAL SURVEY OF ALBERTA, OCCASIONAL PAPER 23.
 
I would    appreciate any assistance in identifying the work done by Justice
or any other experiments with clay pipes and trampling.
 
Thank You
