The Oregon Trail and modern-day Interstate 84 wind and meander through the Blue Mountains in NE Oregon. Here are the oldest mountains in the state. The sub-ranges of the Blue Mountains were once an arc of volcanic islands thousands of miles south and further west in a giant ocean called Panthalassa.
The answer is not simple, as there was no single route, just a destination: Oregon's Willamette Valley. It is on the closest well-maintained road to the actual route of the pioneer emigrants. There are about 300 identical signs across the state of Oregon, showing where modern tourists can parallel the Trail's route.
