Adams in Umatilla County, Oregon — The American West (Northwest)
Whitman Route Oregon Trail 1843-1847
In 1843, the first large party of emigrants, about 1,000, ventured along the Oregon Trail to the Whitman Mission. Only after 1845 did travelers continue west from the base of the Blues near Cayuse through the present locations of Pendleton and Echo. The route to the Whitman Mission was almost due north from Cayuse to the campsite a mile north of this location, and then on to Pine Creek, the Mojonnier crossing of the Walla Walla River, and the mission. Few traveled the route to the mission after it was destroyed in November 1847.
In 1854, Winfield Scott Ebey (and others) followed the same route to Pine Creek, but then veered west to traverse the southern edge of the Walla Walla Valley. Both the mission route and Ebey's route led to the Hudson Bay Company's Fort Walla Walla on the Columbia River.

Here the trail forks, the right hand goes to the Settlement on the Walla Walla River the left is our road. We turn down a dry branch and over a hill 4 miles to a branch & one mile to this camp."
