What river led Lewis and Clark to the Pacific Ocean?

Answer 1

In spring 1805, they continued to the headwaters of the Missouri River, struggled across the Continental Divide at Lemhi Pass, and headed west along the Salmon, Clearwater, Snake, and Columbia Rivers to the Pacific. They landed at the mouth of the Columbia River, Astoria, Oregon on November 5 1805.

Answer 2

The river that led Lewis and Clark to the Pacific Ocean was the Columbia River. It had taken them over a year and a half to make it to the Pacific Ocean from St. Louis, Missouri.

Answer 3

There was no river that took them to the Pacific. I think the Snake was used by them.
