Preceding Context: Over the years many ferries were established to help get across the many rivers on the path of the Oregon Trail. Multiple ferries were established on the Missouri River, Kansas River, Little Blue River, Elkhorn River, Loup River, Platte River, South Platte River, North Platte River, Laramie River, Green River, Bear River, two crossings of the Snake River, John Day River, Deschutes River,
Succeeding Context: , as well as many other smaller streams. During peak immigration periods several ferries on any given river often competed for pioneer dollars. These ferries significantly increased speed and safety for Oregon Trail travelers. They increased the cost of traveling the trail by roughly $30.00 per wagon but increased the speed of the transit from about 160–170 days in 1843 to 120–140 days in 1860. Ferries also helped prevent death by drowning at river crossings.
