Which trail extended from independence, mississippi, to the columbia river in oregon, and covered 2,000 miles of prairies, mountains and deserts?

The Oregon Trail is the trail that extended from Independence, Mississippi, to the Columbia River in Oregon and covered 2000 miles of prairies, mountains and deserts. It is actually the east-west immigration and large wheel wagon route that connected the valleys in Oregon with the Missouri river. I hope the answer helps you.
