The route known as the Oregon Trail followed the Platte River ________.
The route known as the Oregon Trail followed the Platte River across the Great Plains to the Rocky Mountains and then into Oregon along the Snake River. 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 La Grande valley before coming to the Blue Mountains.
