Lewis and Clark continued on and arrived in Washington, D.C. on September 23, 1806. They had fulfilled a President’s dream. Excluding preparation time, their trip (which began in St. Louis on May 14, 1804), had taken nearly 2½ years.
An unprecedented journey, by the Corps of Discovery, paved the way for later life and exploration in the western regions of what is now America. Clark had documented “new” plant and animal life as well as other interesting items (like Indian Petroglyphs engraved in limestone near the mouth of the Nemaha River in modern-day Kansas).
What happened to the leading members of the Expedition?
Although Lewis and Clark were very different individuals, they never quarreled, never lost their admiration for each other and remained friends to the end.
However ... lest we forget the services of the unpaid interpreter and the various Native American tribes ... who can say whether two of America’s greatest explorers would have been so successful had they not had the help of a teenaged Shoshone called Sacajawea?
