The San Bernardinos and their surrounds were sporadically explored throughout the next 50 years or so - first by Francisco Garcés, the first known European to use the Mojave Road, in 1776, followed by José Maria de Zalvidea, who surveyed the Mojave River area in 1806. In 1810, Francisco Dumetz led a small company to build a temporary chapel near what is now Redlands. On May 20, the Feast Day of Bernardino of Siena, Dumetz named the San Bernardino Valley. This name was applied to San Bernardino Peak by 1835, and was in wide use for the entire range by 1849.
