Name four goals that Jefferson had for the Lewis and Clark expedition?

The main goal of the entire expedition was to find an all river route to the Pacific Ocean, which they didn't find.

Other goals were:

1.) To map, measure and mark all rivers, streams, islands, other natural landmarks, etc.

2.) To establish peaceful relations with any Native Americans they may encounter

3.) To write down any useful information about said Natives (agriculture, food, clothing, laws, etc.)

4.) To record any new animals or plant life they may come upon

5.) To record the location of any mineral or metals they may find

6.) To record the climate, the temperature, and season dates of every day of the expedition
