“If we never see each other again, do the best you can, God will take care of us.”
– Patty Reed of the Donner-Reed Party 1846
The California Trail carried over 250,000 gold-seekers and farmers to the goldfields and rich farmlands of the Golden State during the 1840s and 1850s, the greatest mass migration in American history. The general route began at various jumping off points along the Missouri River and stretched to various points in California, Oregon, and the Sierra Nevada. The specific route that emigrants and forty-niners used depended on their starting point in Missouri, their final destination in California, the condition of their wagons and livestock, and yearly changes in water and forage along the different routes. The trail passes through the states of Missouri, Kansas Nebraska, Colorado, Wyoming, Idaho, Utah, Nevada, Oregon, and California.
Before the trail was blazed, the Great Basin region had only been partially explored during the days of Spanish and Mexican rule. However, that changed in 1832 when Benjamin Bonneville, a United States Army officer, requested a leave of absence to pursue an expedition to the west. The expedition was financed by John Jacob Astor, a rival of the Hudson Bay company. While Bonneville was exploring the Snake River in Wyoming, he sent a party of men under Joseph Walker to explore the Great Salt Lake and find an overland route to California.
Early settlers began to use the trail in the 1840s, the first of which was John Bidwell, who led the 1841 Bidwell-Bartleson Party. In 1842, a member of the Bidwell-Bartleson Party returned to Missouri on the Humboldt River Route.
Among them was a man named Joseph Chiles, who would lead another party to California in 1843 and play an important part in the subsequent opening of more segments of the California Trail. Throughout the 1840s settlers would develop short cuts on the route to California. One such short cut, called the Hastings Route, ran south of the main route. This “new” route would spell the death of many of those in the infamous Donner Party.
The main branch of the trail across the Great Plains generally followed the same path as the Oregon and Mormon Trails but extended to California from various points in southern Wyoming and Idaho. The trail followed the Missouri River before crossing the great plains of Nebraska along the Platte and North Platte Rivers to present-day Wyoming. It then followed the Sweetwater River across Wyoming, then northwest along the Snake River to Fort Hall in present-day southeastern Idaho. Fort Hall was the Hudson Bay Company’s post on the Snake River. From here, the primary route followed the Snake River south to American Falls, past Massacre Rocks, and Register Rock to cross the Raft River. After the crossing of the river, the trail split with the Oregon Trail, with the California bound emigrants turning south through the Raft River Valley to the City of Rocks.
The trail then climbed through the Pinnacle and Granite Passes, before dropping down to Goose Creek and meandering south through the northwest corner of Utah and into Nevada. At the headwaters of the Humboldt River in present-day northwestern Nevada the California Trail followed the north bank of the Humboldt River southwest through present-day Elko, Nevada and the narrow Carlin Canyon, where, during periods of high water, the route was almost impassable.
West of Carlin, the California Trail climbed Emigrant Pass, descending into Emigrant Canyon to rejoin the Humboldt River at Gravelly Ford. Here, the route divided to follow the north and south sides of the river, before rejoining at Humboldt Bar. Various routes branched out across the Sierra Nevada, as the emigrants made their way to various destinations in California.
Early emigrants once called the California Trail an elephant, due to the difficult journey. If you wanted to get to California in pre-railroad times, you were guaranteed an arduous trek. California emigrants faced the greatest challenges of all the pioneer emigrants of the mid-19th century. In addition to the Rockies, these emigrants faced the barren deserts of Nevada and the imposing Sierra Nevada Range.
The travelers of the California Trail often quipped that if you had “seen the elephant,” then you had hit some hard traveling.
When gold was discovered at Sutter’s Mill in Coloma, California, the trickle of emigrants became a flood as thousands of prospectors and families made their way to the Golden State in hopes of finding their fortunes. According to some statistics, over 70,000 emigrants used the California Trail in 1849 and 1850 alone.
In the two decades of the 1840s and 1850s, the California Trail carried over 250,000 gold-seekers and farmers to the state’s goldfields and rich farmlands. It was the greatest mass migration in American history.
Eventually, the portions of the railroad followed parts of the California Trail and as the automobile was introduced and began to be used by the masses, highways replaced the trail. Today, U.S. Highways 40 and 80 follow the path of the California Trail.
The California Trail system, which now includes approximately 5,665 miles of trails, was developed over a period of years. Numerous cutoffs and alternate routes were tried along the California Trail to see which was the “best” in terms of terrain, length and sufficient water and grass for livestock.
Today, more than 1,000 miles of trail ruts and traces can still be seen in the vast undeveloped lands between Casper, Wyoming and the West Coast, reminders of the sacrifices, struggles, and triumphs of early American travelers and settlers. About 2,171 miles of this system cross public lands, where most of the physical evidence that still exists today is located, including the names of emigrants written with axle grease on the rocks at the City of Rocks National Reserve in southern Idaho. More than 300 historic sites along the trail will eventually be available for public use and interpretation.
“I think that I may without vanity affirm that I have seen the elephant.”
