The early Mormons traveled along Parley Street as they departed Nauvoo and crossed the Mississippi River into Iowa in 1846. Today, thirty markers along part of the street contain quotes from journals and letters of the early pioneers about their preparations for the great trek to the Rocky Mountains. At the edge of the river stands the Pioneer Memorial and "Exodus to Greatness" Monument.
Each February, local residents, visitors, and missionaries who serve as hosts in Old Nauvoo commemorate the 1846 river crossing with a program at the Family Living Center and then a wagon ride or walk along Parley Street to the river. An outdoor devotional, hymn, and flag ceremony conclude the morning's observance.
