Once across the Snake River ford near Old Fort Boise the weary travelers traveled across what would become the state of Oregon. The trail then went to the Malheur River and then past Farewell Bend on the Snake River, up the Burnt River canyon and northwest to the Grande Ronde Valley near present-day La Grande before coming to the Blue Mountains. In 1843 settlers cut a wagon road over these mountains making them passable for the first time to wagons. The trail went to the Whitman Mission near Fort Nez Perces in Washington until 1847 when the Whitmans were killed by Native Americans. At Fort Nez Perce some built rafts or hired boats and started down the Columbia; others continued west in their wagons until they reached The Dalles. After 1847 the trail bypassed the closed mission and headed almost due west to present-day Pendleton, Oregon, crossing the Umatilla River, John Day River, and Deschutes River before arriving at The Dalles. Interstate 84 in Oregon roughly follows the original Oregon Trail from Idaho to The Dalles.
