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.

Minidoka Internment National Monument was established in 2001 as the 385th unit of the National Park System to commemorate the hardships and sacrifices of Japanese Americans interned there during World War II. Also known as the 'Hunt Camp', the Minidoka Relocation Center was a 33,000-acre site with over 600 buildings and a total population of about 13,000 internees held from Washington, Oregon, and Alaska. It was in operation from August 1942 until October 1945. The Monument is located between the towns of Twin Falls and Jerome, Idaho in south central Idaho.

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.
