California Trail

The California Trail was an emigrant trail of about 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 . By 1847, two former fur trading frontier forts marked trailheads for major alternative routes through Utah and Wyoming to Northern California. The first was Jim Bridger's Fort Bridger (est. 1842) in present-day Wyoming on the Green River, where the Mormon Trail turned southwest over the Wasatch Range to the newly established Salt Lake City, Utah. From Salt Lake the Salt Lake Cutoff (est. 1848) went north and west of the Great Salt Lake and rejoined the California Trail in the City of Rocks in present-day Idaho. The main Oregon and California Trails crossed the Yellow River on several different ferries and trails (cutoffs) that led to or bypassed Fort Bridger and then crossed over a range of hills to the Great Basin drainage of the Bear River (Great Salt Lake). Just past present-day Soda Springs, Idaho, both trails initially turned northwest, following the Portneuf River (Idaho) valley to the British Hudson's Bay Company's Fort Hall (est. 1836) on the Snake River in present-day Idaho. From Fort Hall the Oregon and California trails went about southwest along the Snake River Valley to another "parting of the ways" trail junction at the junction of the Raft and Snake rivers. The California Trail from the junction followed the Raft River to the City of Rocks in Idaho near the present Nevada-Idaho-Utah tripoint. The Salt Lake and Fort Hall routes were about the same length: about . From the City of Rocks the trail went into the present state of Utah following the South Fork of Junction Creek.

California Trail

Sacramento Valley

The Sacramento Valley is the area of the Central Valley of the U.S. state of California that lies north of the Sacramento–San Joaquin River Delta and is drained by the Sacramento River. It encompasses all or parts of ten Northern California counties. Although many areas of the Sacramento Valley are rural, it contains several urban areas, including the state capital, Sacramento. Since 2010, statewide droughts in California have further strained both the Sacramento Valley's and the Sacramento metropolitan region's water security.

Westward Expansion Trails

In the history of the American frontier, pioneers built overland trails throughout the 19th century, especially between 1829 and 1870, 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.
