The Columbia River gorge is a scenic river canyon, 80 miles (129km) long and up to 4,000 feet (1,219m) deep, that’s part of the Oregon Trail. During the 1800s, Old West travellers in search of silver, gold and a better life, would pack up their wagons and follow the 2,200-mile (3,541km) route from Missouri to Oregon. This was before the first transcontinental railroad was completed. Towns, trading posts, military posts and smaller roads, based on Native American routes, sprang off the Oregon Trail.
