This House of Sky: Dupuyer
Dupuyer, unlike Ringling or White Sulphur Springs, seemed never to have had the least hesitation about its livelihood since the first wagon master wearily overnighted on the site sometime in the 1870’s…. The country rimming it to the west was found to be fine for sheep, and a local rancher named Oliver Goldsmith Cooper became president of the potent Montana Wool Growers Association. Before the turn of the century, a quarter million pounds of fleece were being shipped from the Dupuyer Creek ranches each year. (186-187)
