Spanish Fork was settled in 1851 by members of The Church of Jesus Christ of Latter-day Saints as part of the Mormon Pioneers' settlement of Utah Territory. Its name derives from a visit to the area by two Franciscan friars from Spain, Silvestre Vélez de Escalante and Francisco Atanasio Domínguez in 1776, who followed the stream down Spanish Fork canyon with the objective of opening a new trail from Santa Fe, New Mexico, to the Spanish missions in California, along a route later followed by fur trappers. They described the area inhabited by Native Americans as having "spreading meadows, where there is sufficient irrigable land for two good settlements. Over and above these finest of advantages, it has plenty of firewood and timber in the adjacent sierra which surrounds its many sheltered spots, waters, and pasturages, for raising cattle and sheep and horses."
In 1851, some settlers led by William Pace set up scattered farms in the Spanish Fork bottom lands and called the area the Upper Settlement. However, a larger group congregated at what became known as the Lower Settlement just over a mile northwest of the present center of Spanish Fork along the Spanish Fork River.
