The Southern Route of the Mormon Trail followed paths explored by Father Garces and Jedediah Smith. In 1848, Mormon Battalion Captain Jefferson Hunt trailed cattle to Utah on this trail. The Daniel Davis family, also of the Mormon Battalion, followed in a covered wagon - the first American family to travel the route.
In 1851, a wagon train of Mormon pioneers settled San Bernardino Valley. They established farms, ranches, stage stops, mining and freighting interests and started a pony express mail service between Southern California and Utah.
Mormon pioneers who settled here helped change California's main economy to agriculture, establishing California's pioneer era of 1846-1886.
