The 38 sites of Nez Perce National Historical Park are scattered across the states of Idaho, Oregon, Washington and Montana and have been designated to commemorate the stories and history of the Nimiipuu and their interaction with explorers, fur traders, missionaries, soldiers, settlers, gold miners, and farmers who moved through or into the area.

When American immigrants arrived in the Oregon Country during the 1830s and 1840s, Fort Vancouver provided them with essential supplies to begin their new settlements. In 1996, the 366-acre Vancouver National Historic Reserve was established to protect adjacent, historically significant historical areas. It includes Fort Vancouver National Historic Site, as well as Vancouver Barracks, Officers' Row, Pearson Field, The Water Resources Education Center, and portions of the Columbia River waterfront.

As the harbinger of America's westward expansion, the Oregon Trail was the pathway to the Pacific for fur traders, gold seekers, missionaries and others. Beginning in 1841 and continuing for more than 20 years, an estimated 300,000 emigrants followed this route from Independence, Missouri to Oregon City, Oregon on a trip that took five months to complete. The 2,170 mile long trail passes through Missouri, Kansas, Nebraska, Wyoming, Idaho and Oregon.

In 1804, Meriwether Lewis & William Clark began a voyage of discovery with 45 men, a keelboat, two pirogues,and a dog. They departed from Camp Wood located in what was to become Illinois. They traveled over a three-year period through lands that later became 11 states. Most of the trail follows the Missouri & Columbia Rivers. Much has changed in 200 years but trail portions remain intact. At 3700 miles, Lewis & Clark NHT is the second longest of the 23 National Scenic & National Historic Trails. It begins at Hartford, IL & passes through portions of MO, KS, IA, NE, SD, ND, MT, ID, OR, & WA. Many people follow the trail by auto; others find adventure in the sections that encourage boating, biking, or hiking. You can still see the White Cliffs in Montana as Lewis & Clark did. You may stand where they stood looking over the rolling plains at Spirit Mound in South Dakota. You might meet the descendants of the people who hosted Lewis & Clark all along the trail. It remains for your discovery.
