North Central Idaho is an area which spans the central part of the state of Idaho and borders Oregon, Montana, and Washington. It is the southern half of the state's Panhandle region and is rich in agriculture and natural resources. Lewis and Clark traveled through this area on their journey to the Pacific Ocean in September 1805, crossing Lolo Pass and continuing westward in canoes on the Clearwater River. They returned the following spring on their way eastward.
