The Old Spanish Trail, a historic route that connects Santa Fe and California, traces the journey of Spanish and Mexican settlers in the 1800s. It was a regional trade route between the two states, with a notable stop at Antoinette Roboux's ranch on the Gunnison River. The trail was used by a company of sixty-five men for trading purposes, and it was later used by a company of sixty-five women for trading and moving. The trail was a vital link for the exchange of goods, including fur, liquor, and clothing, and it played a significant role in the development of the Old Spanish Trail Association.
