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? ;.) my best, Tim Scarlett
