Inscription.
May 23, 1804, was an eventful day for the Lewis and Clark party. Early in the day they stopped at Boone's Settlement on Femme Osage Creek, though they did not meet Daniel Boone himself. A mile later, the boats passed along Tavern Rocks, a towering set of bluffs on the south side of the river that extended for several miles. Capt. William Clark stepped ashore to explore Tavern Cave, a riverside landmark at the base of the bluffs, while the rest of the party proceeded upstream another mile before halting. On the walls of this sandstone shelter cave, Clark noticed Indian pictographs and the names of French travelers, and left his own name, although none of these inscriptions have ever been identified in today's cave.

Meanwhile, Capt. Meriwether Lewis clambered up the 300-foot-tall, pinnacle-like bluffs. At one point near the top he lost his grip and started to slide backward. Only Clark's journal and field note entries mention this near-disaster - "...he caught at 20 foot [and] Saved himself by the assistance of his Knife." Had Lewis died or been severely injured, the history of the expedition might have been profoundly

different.

Back on the river, the boats struggled through mats of driftwood, called embarras by the French. After covering nine miles for the day, the expedition camped at the base of the bluffs opposite here. That evening, the captains inspected the men's rifles and equipment. The Corps of Discovery was a military expedition and the men were expected to be in constant readiness for any situation, especially considering the rumors the captains had been hearing of an impending war between the Sauk-Fox and Osage Indan tribes.

Lewis and Clark sent two hunters ashore on May 23 to provide the 45 members of the expedition wth fresh meat. While traveling up the Missouri River, small huntnig parties set out each morning wth two horses and moved upriver, parelleling the progress of the boats and searching for game. Reubin Fields shot a deer on this day, the first of many animals brought in for food.

Journals
The co-captains, Meriwether Lewis and Williams Clark, were the principal journal keepers of the Lewis and Clark Expedition. Besides Lewis and Clark, at least four other members of the Corps of Discovery kept journals: Segeants John Ordway, Charles Floyd (who died three months after departure), Patrick Gass (Floyd's replacement) and Pvt Joseph Whitehouse. Lewis was the most literary writer of the party, but his journal has several huge gaps. He wrote virtually nothing in MIssouri after late November 1803. Clark made detailed journal entries for every day of the trek through Missouri once he assumed journal keeping duties from Lewis on Nov. 28, 1803. His writing lacked the flair of Lewis', and his spelling left much to be desired, but he wrote thorough accounts of each day's journey. Often he wrote two or more versions that included entries

in his journal and on loose sheets of papers that are now known as the field notes. In terms of detail, his writing does not take a back seat to that of Lewis, who is sometimes considered to be the superior chronicler. The sergeants' journal entries are usually short and businesslike but do contain information not found in the captains' accounts. Whitehouse was the only writer to give the privates' view of the epic trip. Since Lewis once mentioned seven journal keepers among the enlisted men, it's possible that Sgt. Pryor and Privates Frazer and Willard also kept journals that are undiscovered.
