The Oregon Trail began in St. Louis, Mo., and ended in either the British outpost of Fort Vancouver or in Oregon City, Ore. The trail started in Missouri and then passed through or touched six other U.S. states.
The Oregon Trail was a path used by 19th century settlers who made their way into the Western areas of the United States. The trail passed through Missouri, Kansas, Nebraska, Wyoming and Idaho, and touched parts of Washington and Iowa. The 2,000-mile trail ended in Oregon and took settlers four to six months to travel, with 10 percent of settlers dying en route.
