The Lewis and Clark Expedition, also known as the Corps of Discovery Expedition, was the United States expedition to cross the newly acquired western portion of the country after the Louisiana Purchase. The Corps of Discovery was a select group of U.S. Army and civilian volunteers under the command of Captain Meriwether Lewis and his close friend Second Lieutenant William Clark. Clark and 30 members set out from Camp Dubois, Illinois, on May 14, 1804, met Lewis and ten other members of the group in St. Charles, Missouri, then went up the Missouri River. The expedition crossed the Continental Divide of the Americas near the Lemhi Pass, eventually coming to the Columbia River, and the Pacific Ocean in 1805. The return voyage began on March 23, 1806, at Fort Clatsop, Oregon, and ended on September 23 of the same year.
Meriwether Lewis was an American explorer, soldier, politician, and public administrator, best known for his role as the leader of the Lewis and Clark Expedition, also known as the Corps of Discovery, with William Clark. Their mission was to explore the territory of the Louisiana Purchase, establish trade with, and sovereignty over the natives near the Missouri River, and claim the Pacific Northwest and Oregon Country for the United States before European nations. They also collected scientific data, and information on indigenous nations. President Thomas Jefferson appointed him Governor of Upper Louisiana in 1806. He died of gunshot wounds in what was either a murder or suicide, in 1809.
Toussaint Charbonneau was a Canadian-born explorer, fur trapper and merchant who is best known for his role in the Lewis and Clark Expedition as the husband of Sacagawea.

Fort Mandan was the name of the encampment which the Lewis and Clark Expedition built for wintering over in 1804–1805. The encampment was located on the Missouri River approximately twelve miles (19 km) from the site of present-day Washburn, North Dakota, which developed later. The precise location is not known for certain. It is believed now to be under the water of the river. A replica of the fort has been constructed near the original site.
Lomatium is a genus in the family Apiaceae. It consists of about 100 species native to western Northern America and northern Mexico. Its common names include biscuitroot, Indian parsley, and desert parsley. It is in the family Apiaceae and therefore related to many familiar edible species such as carrots and celery; some Lomatium species are extensively used by Native Americans in the inland Northwest as a staple food.

The leaves emerge from the lower part of the stem. Each is generally divided into three leaflets which are each subdivided into three linear leaflike segments. The inflorescence is an umbel of yellow flowers, each cluster on a ray up to 10 centimeters long, altogether forming a flat formation of umbels.
