context_page_description: The Oregon Trail is a 2,170-mile historic east-west, large-wheeled wagon route and emigrant trail in the United States that connected the Missouri River to valleys in Oregon. The eastern part of the Oregon Trail spanned part of the future state of Kansas, and nearly all of what are now the states of Nebraska and Wyoming. The western half of the trail spanned most of the future states of Idaho and Oregon.
  The Oregon Trail was laid by fur traders and trappers from about 1811 to 1840, and was only passable on foot or by horseback. By 1836, when the first migrant wagon train was organized in Independence, Missouri, a wagon trail had been cleared to Fort Hall, Idaho. Wagon trails were cleared increasingly farther west, and eventually reached all the way to the Willamette Valley in Oregon, at which point what came to be called the Oregon Trail was complete, even as almost annual improvements were made in the form of bridges, cutoffs, ferries, and roads, which made the trip faster and safer.
context_section_description: In what was dubbed "The Great Migration of 1843" or the "Wagon Train of 1843", an estimated 700 to 1,000 emigrants left for Oregon. They were led initially by John Gantt, a former U.S. Army Captain and fur trader who was contracted to guide the train to Fort Hall for $1 per person. The winter before, Marcus Whitman had made a brutal mid-winter trip from Oregon to St. Louis to appeal a decision by his mission backers to abandon several of the Oregon missions. He joined the wagon train at the Platte River for the return trip. When the pioneers were told at Fort Hall by agents from the Hudson's Bay Company that they should abandon their wagons there and use pack animals the rest of the way, Whitman disagreed and volunteered to lead the wagons to Oregon. He believed the wagon trains were large enough that they could build whatever road improvements they needed to make the trip with their wagons. The biggest obstacle they faced was in the Blue Mountains of Oregon where they had to cut and clear a trail through heavy timber. The wagons were stopped at The Dalles, Oregon, by the lack of a road around Mount Hood. The wagons had to be disassembled and floated down the treacherous Columbia River and the animals herded over the rough Lolo trail to get by Mt. Hood. Nearly all of the settlers in the 1843 wagon trains arrived in the Willamette Valley by early October. A passable wagon trail now existed from the Missouri River to The Dalles. Jesse Applegate's account of the emigration, "A Day with the Cow Column in 1843," has been described as "the best bit of literature left to us by any participant in the [Oregon] pioneer movement..." and has been republished several times from 1868 to 1990.
  In 1846, the Barlow Road was completed around Mount Hood, providing a rough but completely passable wagon trail from the Missouri River to the Willamette Valley: about 2,000 miles (3,200 km).
