The present day Fort Vasquez located, literally, on Highway 85, next to Platteville, Colorado is a reconstruction of the adobe trading post established by the trappers Louis Vasquez and Andrew Sublette. They built the fort in 1835 after obtaining a trading license in St. Louis, Missouri, from William Clark, the Superintendent of Indian Affairs. They traded with other furriers, trappers, mountain men, and Native American tribes (including the Arapaho and Cheyenne), amidst competition with other trading posts. Unable to turn a profit, they sold Fort Vasquez to Lock and Randolph in 1840 who subsequently went bankrupt and abandoned the structures in 1842. Due to the bankruptcy, Vasquez and Sublette could not collect the sum owed to them for the sale.
