U.S. Department of the Interior(@Interior):The Pacific Ocean! Well, almost. On Nov. 7, 1805, Lewis and Clark thought they'd reached the Pacific. But they were still 20+ miles away. What they saw was the widening mouth of the Columbia River. Today, much of that landscape is protected by Lewis and Clark National Wildlife Refuge.
