Lemhi Pass, Montana & Idaho: August 12, 1805

At this point, the Corps of Discovery crossed the Continental Divide and entered the Pacific Ocean drainage system. They also left territory that belonged to the United States. All that could be seen to the west from Lemhi Pass were jagged mountain peaks that stretched to the horizon. It was now obvious that there was no practical Northwest Passage to the Pacific.
