Oregon Trail Route: Interstate 84 Professional Review and Guide
"A 190-mile drive on paved roads through desert, grasslands, and over the Blue Mountains while following the route of the Oregon Trail. From 1841 through 1884, the Oregon Trail was the major east-west route from the Idaho border to Portland. The route parallels and overlaps portions of the trail between Farewell Bend State Park and Pendleton. The original trail followed centuries-old Indian paths that had been used by early explorers and fur traders, and wove over mountain passes, through valleys, and across rivers formed by more than 200 million years of geologic activity. The shape of the land has dictated routes of travel from the dawn of man to today.
From Ontario to Ladd Canyon, south of La Grande, the highway crosses flat desert, wide valleys, rolling sand, gray and brown hills and mountains. It is a land of little water, covered with sparse pale grass sprinkled with juniper trees. Between La Grande and Pendleton, the route climbs high into the Blue Mountains then abruptly descends to flat fields.
