1828 Four French traders from Kentucky -- William "Toopeechee" Reed, Jim Reed, Dennis Julien, and Augustus Archambeaux -- entered the Uintah Basin and set up a trading post near a spring of water just south and east of the present settlement of Whiterocks. The site was at a junction of trails used by the local Ute people. They brought in the first butcher knives, coffee beans, and other articles traded to the locals for fur. Antoine Robidoux (or Rubidoux) purchased the enterprise in 1832 and built a larger "fort" just east of the post named Fort Robidoux (or Fort Uinta). In 1844, Utes burned the trading post to the ground and it was not rebuilt.
