Muddy Creek Camp and Crossing, on the west side of Muddy Creek, was used by Brigham Young's first group of Mormon pioneers when they arrived on July 9, 1847. Thomas Bullock reported that the brethren sang hymns for President Brigham Young and had a delightful evening, while Erastus Snow called the campground very pretty. With good water, plenty of grass, and tall bunch-grass along the creek that fed the animals well, it became one of the most heavily used camps on the Overland-Mormon-California-Pony Express Trails. Approximately 70,000 Mormon pioneers crossed, passed through, or camped there. The U.S. Army camped there with 2,000 men in June 1858, and both the Martin and the Willie handcart companies crossed there in November 1856 while traveling with rescue wagons. The Muddy Overland Stage Stop and Pony Express Station stood at the site, with foundation stones that may still be seen along the west bank of Muddy Creek. The original Transcontinental Railroad bed of 1869 followed the road there, and the Transcontinental Telegraph, automobile road, and stageline either passed through the campground or lay very nearby, making Muddy Creek Camp an important part of the area's history.
