Thank you Meriwether and William

On this date in 1804, the Lewis and Clark expedition leaves St. Louis, Missouri, on a mission to explore the Northwest from the Mississippi River to the Pacific Ocean.

The expedition traveled up the Missouri River in a 55-foot long keelboat and two smaller boats.

On September 23, 1806, after almost two and a half years, the expedition returned to the city, bringing back a wealth of information about the largely unexplored region, as well as valuable U.S. claims to Oregon Territory.

Now that's what I call a slow mosey!
