Although the City's history is short, the history of the valley in which it resides is rich. Even before the Mormon pioneers arrived in 1847, Native American tribes inhabited the area and Mexican traders had established trading routes. The first federal military post in Utah, Camp Floyd,  was established in the southwestern portion of the valley. At its high  point, Camp Floyd housed one third of the country's army reserves and  boasted 3,500 troops and officers, 500 wagons, 600 horses and 3,000  mules-not to mention the merchants and camp followers that pushed the  community population to nearly 7,000.
                    The  valley is most famous for the Pony Express Trail, which crossed through  the central part of the valley. In honor of this history, Eagle  Mountain City annually celebrates its Pony Express Days in June.
                    Today,  people move to Eagle Mountain for its wide-open spaces and quality of  life. Even with an average issuance of 40+ residential building permits a  month, the sheer size Eagle Mountain promises room for anyone who wants  to raise a family in a master-planned community that incorporates the  technology of today and tomorrow with the values from the past.
