With the arrival of American explorers, traders and trappers in the early 19th century, the old Indian campground became the site of several temporary structures: the 1806 breastwork of Zebulon Pike, the 1820 cabin of Jacob Fowler, the log trading posts of three competing trading houses, the adobe Pueblo of independant traders, the cottonwood cabins of Mormontown, and the gold rush town of Fountain City.
