Early Idaho History: Lewis & Clark
Idaho history always begins with the bold expedition carried out by Lewis and Clark in the early 1800's.
It is believed that the two heroic explorers Captains Meriwether Lewis and William Clark were the first Euro-Americans to view what is now known as Idaho. The year was 1805.
Resulting from the Louisiana Purchase, Lewis and Clark were dispatched out by President Thomas Jefferson to discover a new overland route to the Pacific Ocean. U.S. Route 12 virtually follows the expedition’s path across the breadth of north central Idaho from Lolo Pass in the Bitterroot Mountains to the state’s western city of Lewiston.
In what is now known as Idaho, Native American tribes, with the names Nez Perce, Coeur d’Alene, Kootenai, Salish, Shoshone and Piute had been living on these lands for centuries.
This drive along the route of Lewis and Clark has unsurpassed scenic splendor and great historic significance for any student of Idaho history. Hundreds of vacationing families travel this route each year. Many highlights of the Lewis and Clark Trail can be found along the way.

The Lewis and Clark expeditionary group of 29 departed St. Louis, Missouri in May 1804. They followed the Missouri River northwest and spent the winter of 1804-05 at a fort just north of present-day Bismarck, North Dakota. While staying at the fort, they visited the Indian villages of the Hidatsa and Mandan tribes, both located near the confluence of the Missouri and Knife Rivers.
There, they met and hired French trader Toussaint Charbonneau as their interpreter and guide. The French trader's young wife, Sacajawea, a Lemhi Shoshone, had been kidnapped as a young girl and taken from her Idaho home. She would accompany her husband and the group and prove to be a valuable asset to the expedition when they reached her native homeland.
The expedition crossed the Continental Divide on August 12, 1805 at Lemhi Pass on what would become the Montana/Idaho border. In this early Idaho history, they were entering the lands of the Lemhi Shoshone, the Salish, and the Nez Perce people. The success of the expedition would ultimately rely on the good will of these Native Americans. But, even with native assistance, this search for the Northwest Passage would prove to be the most difficult part of this heroic journey.
The story of the Lewis and Clark Expedition through Idaho is one of brazen courage and challenge, loss and triumph. Much of the landscape traversed by the explorers in 1805-06 is unchanged today. One can still find the scenic rivers, the majestic mountains, the deep canyons and the rolling hills that these intrepid people viewed and endured during their trek.
