They were hired to accomplish 5 goals: find the source of the Missouri River, cross the rocky mountains, follow the largest river west to the Pacific Ocean, establish trade with the native peoples, and lastly assure the Native Americans of the peaceful intentions of the United States.
Sir Alexander MacKenzie (1764 - March 11, 1820) became the first European to cross the Rocky Mountains in 1793.
The white cross at Mt York in the Blue Mountains was placed there in memory of the death of the son of a significant Sydney businessman, Henry Marcus Clark. Clark had several children who were quite experienced at exploring and traversing the rocky ledges and mountainsides of the Blue Mountains, but one day his 6 year old son Byron followed his elder siblings in their adventures. Needless to say, he fell when a rock ledge collapsed beneath his feet. He died whilst being carried back to the top of the mountain.

It is important to note that Meriwether Lewis couldn't have completed the expedition without the help of William Clark and Sacagawea. In fact, President Thomas Jefferson asked Lewis to lead the expedition, but Lewis wanted help from Clark. The Lewis and Clark Expedition of 1804-1805 gave people an idea of what the Great Plains was like. If they hadn't made that expedition, it probably would have been much longer before pioneers attempted to cross to California and the Pacific Northwest, as well as the fact that it would have been longer before people settled in the Great Plains. They also established friendly relations with many of the tribes, which made it safer for those who would travel and settle in the frontier. However, the expedition was of no benefit to the Native Americans, and only accelerated the speed at which they were driven from their land and their way of life.
