On this day with Lewis & Clark

December 11, 1803

St. Louis fanfare

From Cahokia, Clark takes the boats across the Mississippi and arrives in St. Louis under full sails and colors. Many people come to the landing to greet them.

December 11, 1804

Sun dogs

At Fort Mandan below the Knife River Villages, rings appear around the sun when its light hits ice crystals suspended in the air. Due to the cold, Clark orders all the hunters to return to the fort.

December 11, 1805

Putting up huts

At the Fort Clatsop construction site on the present Lewis and Clark River, rains are constant as the men put up the huts. Several of the enlisted men are sick or injured.

Winter at Fort Mandan

26 October 1804–6 April 1805

On 2 November 1804 below the Knife River Villages, work begins on the expedition’s winter fortification. The men’s quarters, storage rooms, and the 16-foot pickets, are designed for defense against hostile Indians, especially the Sioux, who would be quite troublesome, although they never attacked the fort directly. “This place we have named Fort Mandan,” Lewis recorded, “in honour of our Neighbours”—their kind and congenial Mandan Indians. Here they celebrate their second Christmas and New Year’s Day.

    Hugh Hall

    Private

    As if to confirm the captains’ poor evaluation of the new arrivals from Fort Southwest Point, a scant nine days after his arrival, Hall was among a group of six or seven men who got drunk on New Year’s Eve.

    Thomas Howard

    Private

    On 23 January 1806, Lewis dispatched Howard and Werner to the Salt Camp on the ocean beach, to bring back a supply of salt. When they had not returned by the 26th, Lewis feared they had gotten lost.

    John Shields

    Private

    During the damp winter at Fort Clatsop and throughout 1806, the journals speak more and more often about Shields’ life-sustaining work as gunsmith. Certainly the guns had seen hard use.

Historical artist Roger Cooke worked with the Washington State Historical Society to recreate several Lewis and Clark scenes of their trek in Washington and Oregon. His art is featured on many interpretive signs at waysides throughout this area of the historic trail. Cooke’s works bring people to the forefront of the Lewis and Clark story. His illustrations feature not just the expedition members but Nez Perce, Palouse, Yakama, Wanapum, Walla Walla, Umatilla, Tenino, Wishram, and various Upper and Lower Chinook Peoples. He displays a full spectrum of emotions—even smiling Indians!—and multi-generational families near their villages. These are stories that modern cameras and digital editing cannot capture.

    The Fur Trade

    Given President Jefferson’s directive to establish commerce, the captains worked extensively within a long-established network of North American fur trade. Part of their mission was to help establish the United States of America’s position within that industry.

    The Arts

    Because of the literate journalists, historians and visual artists can tell the Expedition’s story. When they celebrated with song and dance, we too can share in the experience.

    Medicine on the Trail

    From major crisis such as the death of Sgt. Floyd, Lewis’s gunshot wound, and the illness of Sacagawea to minor events such as sexually transmitted diseases, mosquito-born illnesses, and deep cuts, the medical aspects of the Lewis and Clark Expedition provide an interesting topic of study.

    Hunting and Fishing

    Although hunting and fishing were often considered a ‘gentleman’s sport’ especially in Europe, hunting and fishing for Native Americans and Americans alike were a matter of survival. The success of the Lewis and Clark Expedition depended on the success of its hunters.

    Horse Travel

    To cross the Rocky Mountains, the Lewis and Clark Expedition needed horses and the skills to manage them. Despite their seemingly constant struggle to find missing and stolen horses, as a kind of calvary unit, they left hoof prints on approximately 1,500 miles of western terrain.

    Native American Nations

    The Lewis and Clark Expedition benefited from the Indians’ knowledge and support. Maps, route information, food, horses, open-handed friendship—all gave the Corps of Discovery the edge that spelled the difference between success and failure.

    The Boats

    Starting at Pittsburgh, traveling to the Pacific Ocean, and then returning to St. Louis, the Lewis and Clark Expedition traveled approximately 10,600 miles. Of that, 85%—over 9,000 miles—was by boat. To understand travel in the early 1800 American West is to understand the boats and challenges of river navigation.

    People

    The success of the Lewis and Clark Expedition was due to its many members and the people they met, including politicians, Eastern gentleman scientists, traders, and the many people already living in the American west.

    Louisiana’s Purchase

    The President’s representatives in Paris had bargained successfully with Napoleon’s bureaucrats not only to buy the port of New Orleans, then the keystone of the continent, but also to acquire, at three cents an acre, an area extending from the Mississippi River to . . . where? No one knew until Meriwether Lewis stood at the crest of the Rocky Mountains at a place known today as Lemhi Pass, on 12 August 1805.

    Legacies

    Legacy is a very slippery sort of term. If we could erase our myth concepts of Lewis and Clark … it might reawaken something really extraordinary in our national consciousness.

    The Trail

    Starting with its genesis in Jefferson’s Monticello, Lewis’s training and preparations in Philadelphia, and the barge’s excursion down the Ohio River, the route they took, often called the Lewis and Clark Trail, crosses the continent weaving an epic tale of western exploration treasured by many today.
