The Oregon Trail was a 2,170-mile (3,490 km) east–west, large-wheeled wagon route and emigrant trail in the United States that connected the Missouri River to valleys in Oregon Territory. The eastern part of the Oregon Trail crossed what is now the states of Kansas, Nebraska, and Wyoming. The western half crossed the current states of Idaho and Oregon.
The Donner Party, sometimes called the Donner–Reed Party, were a group of American pioneers who migrated to California in a wagon train from the Midwest. Delayed by a multitude of mishaps, they spent the winter of 1846–1847 snowbound in the Sierra Nevada. Some of the migrants resorted to cannibalism to survive, mainly eating the bodies of those who had succumbed to starvation, sickness, or extreme cold, but in one case two Native American guides were murdered and eaten.
The California Trail was an emigrant trail of about 1,600 mi (2,600 km) across the western half of the North American continent from Missouri River towns to what is now the state of California. After it was established, the first half of the California Trail followed the same corridor of networked river valley trails as the Oregon Trail and the Mormon Trail, namely the valleys of the Platte, North Platte, and Sweetwater rivers to Wyoming. The trail has several splits and cutoffs for alternative routes around major landforms and to different destinations, with a combined length of over 5,000 mi (8,000 km).
Donner Pass is a 7,056-foot-high (2,151 m) mountain pass in the northern Sierra Nevada, above Donner Lake and Donner Memorial State Park about 9 miles (14 km) west of Truckee, California. Like the Sierra Nevada themselves, the pass has a steep approach from the east and a gradual approach from the west.
Donner Lake, formerly known as Truckee Lake, is a freshwater lake in Northeast California on the eastern slope of the Sierra Nevada and about 20 miles (32 km) northwest of the much larger Lake Tahoe. A moraine serves as a natural dam for the lake. The lake is located in the town of Truckee, between Interstate 80 to the north and Schallenberger Ridge to the south. The tracks of the Union Pacific Railroad run along Schallenberger Ridge and closely follow the route of the original transcontinental railroad. The historic route of the Lincoln Highway, the first automobile road across America and US 40 follows the northern shoreline, then climbs to Donner Pass from where the entire lake may be viewed.
Donner Memorial State Park is a state park of California, US, preserving the site of the Donner Camp, where members of the ill-fated Donner Party were trapped by weather during the winter of 1846–1847. Caught without shelter or adequate supplies, members of the group resorted to cannibalism to survive. The Sierra Nevada site has been designated a National Historic Landmark. The state park contains the Emigrant Trail Museum and the Pioneer Monument dedicated to the travelers of the Emigrant Trail.
State Route 20 is a state highway in the northern-central region of the U.S. state of California, running east–west north of Sacramento from the North Coast to the Sierra Nevada. Its west end is at SR 1 in Fort Bragg, from where it heads east past Clear Lake, Colusa, Yuba City, Marysville and Nevada City to I-80 near Emigrant Gap, where eastbound traffic can continue on other routes to Lake Tahoe or Nevada.
Meek Cutoff was a horse trail road that branched off the Oregon Trail in northeastern Oregon and was used as an alternate emigrant route to the Willamette Valley in the mid-19th century. The road was named for frontiersman Stephen Meek, who was hired to lead the first wagon train along it in 1845. The journey was a particularly hard one, and many of the pioneers lost their lives.
State Route 88 (SR 88), also known as the Carson Pass Highway, is a state highway in the U.S. state of California. It travels in an east–west direction from Stockton, in the San Joaquin Valley, to the Nevada state line, where it becomes Nevada State Route 88, eventually terminating at U.S. Route 395 (US 395). The highway is so named as it crests the Sierra Nevada at Carson Pass. The highway corridor predates the era of the automobile; the path over Carson pass was previously used for the California Trail and the Mormon Emigrant Trail. The mountainous portion of the route is included in the State Scenic Highway System.
The Death Valley '49ers were a group of pioneers from the Eastern United States that endured a long and difficult journey during the late 1840s California Gold Rush to prospect in the Sutter's Fort area of the Central Valley and Sierra Nevada in California. Their route from Utah went through the Great Basin Desert in Nevada, and Death Valley and the Mojave Desert in Southern California, in attempting to reach the Gold Country.
Beckwourth Pass is the lowest mountain pass in the Sierra Nevada mountain range at an elevation of 5,221 feet (1,591 m).
Caleb Greenwood was a Western U.S. fur trapper and trail guide.
The Stephens–Townsend–Murphy Party consisted of ten families who migrated from Iowa to California prior to the Mexican–American War and the California Gold Rush. The Stephens Party is significant in California history because they were the first wagon train to cross the Sierra Nevada during the expansion of the American West. In 1844, they pioneered the first route at or near what was later named Donner Pass. The crossing was a year before the third expedition of John Charles Frémont, two years before the Donner Party, and five years before the 1848–49 Gold Rush. Three other known European exploration crossings of the Sierra Nevada had previously occurred at points south of this however, including Frémont's second expedition the previous winter, at Carson Pass.
U.S. Route 50 (US 50) is a transcontinental United States Numbered Highway, stretching from West Sacramento, California, in the west to Ocean City, Maryland, in the east. The California portion of US 50 runs east from Interstate 80 (I-80) in West Sacramento to the Nevada state line in South Lake Tahoe. A portion in Sacramento also has the unsigned designation of Interstate 305. The western half of the highway in California is a four-or-more-lane divided highway, mostly built to freeway standards, and known as the El Dorado Freeway outside of downtown Sacramento. US 50 continues as an undivided highway with one eastbound lane and two westbound lanes until the route reaches the canyon of the South Fork American River at Riverton. The remainder of the highway, which climbs along and out of the canyon, then over the Sierra Nevada at Echo Summit and into the Lake Tahoe Basin, is primarily a two-lane road.
Joseph R. Walker was a mountain man and experienced scout. He established the segment of the California Trail, the primary route for the emigrants to the gold fields during the California gold rush, from Fort Hall, Idaho to the Truckee River. The Walker River and Walker Lake in Nevada were named for him by John C. Frémont.
The Emigrant Trail in Wyoming, which is the path followed by Western pioneers using the Oregon, California, and Mormon Trails, spans 400 miles (640 km) through the U.S. state of Wyoming. The trail entered from Nebraska on the eastern border of the state near the present day town of Torrington and exited on the western border near the towns of Cokeville and Afton. An estimated 350,000 to 400,000 settlers traveled on the trail through Wyoming between 1841 and 1868. All three trails follow the same path through most of the state. The Mormon Trail splits at Fort Bridger and enters Utah, while the Oregon and California Trails continue to Idaho.
In the history of the American frontier, pioneers built overland trails throughout the 19th century, especially between 1840 and 1847 as an alternative to sea and railroad transport. These immigrants began to settle much of North America west of the Great Plains as part of the mass overland migrations of the mid-19th century. Settlers emigrating from the eastern United States did so with various motives, among them religious persecution and economic incentives, to move from their homes to destinations further west via routes such as the Oregon, California, and Mormon Trails. After the end of the Mexican–American War in 1849, vast new American conquests again encouraged mass immigration. Legislation like the Donation Land Claim Act and significant events like the California Gold Rush further encouraged settlers to travel overland to the west.
Martin Creek, known locally as Dennis Martin Creek, is a 1.4-mile-long (2.3 km) north by northeastward-flowing stream originating just east of Skyline Boulevard in the Santa Cruz Mountains, near the community of Skylonda in San Mateo County, California. It flows through the town of Woodside before crossing Portola Road and joining Sausal Creek on Stanford University lands just across the border from Woodside. Sausal Creek enters Searsville Reservoir, which flows to San Francisco Bay via San Francisquito Creek.
Mormon Road, also known to the 49ers as the Southern Route, of the California Trail in the Western United States, was a seasonal wagon road pioneered by a Mormon party from Salt Lake City, Utah led by Jefferson Hunt, that followed the route of Spanish explorers and the Old Spanish Trail across southwestern Utah, northwestern Arizona, southern Nevada and the Mojave Desert of California to Los Angeles in 1847. From 1855, it became a military and commercial wagon route between California and Utah, called the Los Angeles – Salt Lake Road. In later decades this route was variously called the "Old Mormon Road", the "Old Southern Road", or the "Immigrant Road" in California. In Utah, Arizona and Nevada it was known as the "California Road".
Murphy's Ranch, also called Murphy's Corral, is a historical site in Elk Grove, Sacramento County, California. The site of Murphy's Ranch is a California Historical Landmark No. 680 listed on May 11, 1959. At Murphy's Ranch on June 10, 1846, was the start of the Bear Flag Revolt and Bear Flag Rebellion.
