Although trappers and traders traversed and used this area in the early 19th century, by far the largest push of humans through the region came as a result of the Oregon Trail. Over 200,00 people are estimated to have traveled the trail between 1840 and 1870. The remnants of the trail can clearly be seen in the Steamboat Lake area of the Refuge.
