In the "Wagon Train of 1843", some 700 to 1,000 emigrants headed for Oregon; missionary Marcus Whitman led the wagons on the last leg. In 1846, the Barlow Road was completed around Mount Hood, providing a rough but passable wagon trail from the Missouri River to the Willamette Valley: about 2,000 miles (3,200 km). Though the main direction of travel on the early wagon trails was westward, people also used the Oregon Trail to travel eastward. Some did so because they were discouraged and defeated. Some returned with bags of gold and silver. Most were returning to pick up their families and move them all back west. These "gobacks" were a major source of information and excitement about the wonders and promises—and dangers and disappointments—of the far West.
