Although I have never worked on a wool site myself, I have a thought or
two about some reverse linkages.  We have had very little manufacturing of
wool products here in the industrial sense, though there have been native
practices for several hundred years.  However we have had a great deal of
industrial level sheep ranching.  Of particular note for the archaeology
types are the remnants of the sheep hearders' camps.  There are some clear
links to the study of ethnicity here.  The Basque sheepmen would travel to
certain camps every year.  These camps sometimes had permanent stone bread
ovens in them. One thing that Nevadans are also rather proud of are the
tree carvings that the Basque men made in certain hardwood trees by
incising the bark.  You could consider these items to be artifacts of the
culture of the workplace:  loneliness, solitude, etc.  I think that all
of these related sites- the pastures, the trails, the art, the camps,
the archaeological sites are all parts of the sociotechnical system of
sheep production.  But you could also push this link to include
the entire Basque culture in our towns- the presence of hotels as social
meeting places and the ritual or traditional dance festivals.  Could you
consider all of these cultural forms linkages, I wonder?  I guess someone
who knows more about these types of things could chime in.
 
Since the Asquaga family made their fortune in sheep ranching, does that
make John Asquaga's Nugget Hotel and Casino a forward linkage? ;.)
