  • September 7: The explorers see their first prairie dog town; the next day, Clark kills his first bison.
  • September 25: Hostility arises in a council with Teton Lakota Indians when they demand a boat from the expedition, but their chief, Black Buffalo, managed to calm them.

  • November 2: They begin to build Fort Mandan 6 miles south of the Knife River to stay in for the winter, and enlist French Canadian Toussaint Charbonneau and his Shoshone wife Sacagawea to join them as interpreters.

1805

  • April 7: 31 men plus Sacagawea and her son Pomp set out westward in canoes. Lewis and Clark send a return party back to St. Louis with pelts, skeletons, soil, plants, minerals, artifacts, maps, letters, journals, and even live animals (most of which didn’t make it) intended for the President.
  • April 25: The Corps of Discovery arrives at the Yellowstone River, 1888 miles from St. Louis.

  • June 16-July 14: The crew must drag thousands of pounds of equipment, which had previously been transported by canoes, on an 18-mile detour around the Great Falls. The facts that Lewis tried and failed to build an iron-frame boat and that many men were injured in the ordeal created significant delays.

  • November 2: The explorers pass the furthest point reached by George Vancouver’s 1792 expedition.
  • November 7: In his journal, Clark writes, “Ocian in view! O! the joy”, but the sea still 20 miles away and bad weather slows their progress.

  • December 7: The crew begins work on their winter camp named after the local Clatsop Indians on the south bank of the Columbia.
  • December 25th: The crew moves into Fort Clatsop.

Winter at Fort Clatsop

  • The winter at Fort Clatsop was cold and rainy according to the expedition team. One expeditioner, Patrick Gass, recorded that “from the 4th of November to the 25th of March 1806, there were not more than twelve days in which it did not rain, and of these but six were clear”.
  • During all the “free time” he had for winter to pass over, Clark was able to compile all the notes he took from the journey to complete a map from Fort Mandan to Fort Clatsop, which would be very helpful to future travelers.
  • In order to survive, people apart of the expedition had to hunt for meat and for trading with the local Clatsop Indians.
  • Right before Lewis and Clark left, they gave Fort Clatsop to the Clatsop Chief Coboway for all of his peoples help with getting them through the winter.

1806

  • March 23: The expedition prepares to go home and hands over Fort Clatsop to the Clatsop Indian Tribe.
    • This was the perfect time for the expedition to leave. If they had left to early, snow would still have blocked their path through the mountains. If they had left too late, they would have been caught in winter on the unsettled prairies.
  • May 9: They stay at Camp Chopunnish near the Nez Perce, waiting for the snow to melt in the Rockies.
  • July 3: The crew splits into two parties: Lewis continues east along the Marias River while Clark follows the Yellowstone River down south.
  • July 27: Having camped with Blackfeet warriors the previous night and waking up with their rifles stolen, Joseph Field kills one of the Indians while Lewis mortally wounds another. They hastily ride back to the main party.
  • August 12: Lewis and Clark are reunited. After two days they arrive back at the Mandan villages.
  • August 17: The crew leaves camp and Mandan chief Big White agrees to go with them back to Washington.
  • September 17: Lewis and Clark learn that many Americans presume them dead.
  • September 23: After weeks of signs of American settlement, the expedition finally arrives in St. Louis. The Corps of Discovery disbands, Lewis is named governor of the Louisiana Territory, and Clark is appointed Indian agent for the West.

Significance of Lewis and Clark’s Expedition

Lewis and Clark’s Expedition across America has been romanticized, demonized, and everything in between. Many people think the expedition was the physical start of manifest destiny in the American culture, which brought the extermination of cultures, bison and prairie lands. Many others see it as a true tale of American exceptionalism overcoming adversity. Both of these ways of looking at it might have some truth, and some embellishments; however, amid all the excitement and folklore over the expedition, I think there is at least one thing that professors and students can gain from the Lewis and Clark Expedition. That one thing is that nothing beats a good journal entry. Historian Donald Jackson stated that Lewis, Clark, and the rest of the team were the heaviest writers in exploration history. They documented every new or major thing they saw, whether it be the vast plains, the strange animals, the unique vegetation, or the enormous mountain ranges. They captured and preserved as much as they could, and then had notes good enough to report back to the President of the United States. These notes are still useful to researchers today. Lewis and Clark set a good example for field researchers like us: journal everything!

Although Clark’s journals are somewhat sparse, Lewis trained as a naturalist and took copious notes on the specimens he collected. Some days were a lot less eventful and I’m sure that some days his sickness prevented him from witnessing everything. Also, many things they saw were so new they were difficult to describe. This makes his journaling job even more difficult, since it would force them to pick and choose what they would journal; however, one thing is for certain, Lewis and Clark’s journals provide a great example of how important good notes are to biological and geographic exploration and study.
