8. The Sacramento River helped form the track of a
trade and travel route known as the Siskiyou Trail, which stretched from
California's Central Valley to the Pacific Northwest. The Siskiyou Trail
closely paralleled the Sacramento River and took advantage of the
valleys and canyons carved by the river through the rugged terrain of
Northern California. Based on the original footpaths of American
Indians, the Siskiyou Trail was expanded by Hudson's Bay Company
trappers in the 1820s, and expanded further by California Gold Rush
"Forty-Niners" in the 1850s. Today, Interstate 5 and the Union
Pacific Railroad occupy the path of the ancient Siskiyou Trail.
