Under the leadership of Brigham Young, the "Mormon" pioneers exploring their way to the Valley of the Great Salt Lake passed here July 15 to 20, 1847. Orson Pratt's advance company reached here July 15, with others following at intervals. The rear company, including Brigham Young, who was ill with mountain fever, encamped near here July 20. At this point the trail turned left to avoid Weber Canyon, then impassable to wagon trains, ascending Henefer Creek to its head and passing from there into East Canyon approximately along the route now traversed by the highway.
