Exploring for economic opportunities, Lewis & Clark found farming, trading for furs and mining as the three main sources of income in the Louisiana Purchase region. President Thomas Jefferson's goals for the expedition included searching out all prospects "for the purpose of commerce."
Residence of the new territory famed for subsistence because food supplies and markets were to far away, but great profit could be made in trading for furs. Beaver, mink raccoon and otter were found throughout the land. Small traders would invest merchandise then travel upstream to trade. The furs were pressed into 80- to 100-pound bales and transported back to St. Louis for sale to the European market.
The third source of income, mining for metals or ore, was aso a strong interest. From the French, Lewis and Clark had learned of locations on the Missouri River with large amounts of lead ore or galena. One site was near the Mine or Lamine River. Most likely, the information came from Etienne de Bourgmont's 1714 report as he explored the Missouri River. These and other natural resources would become valuable commerce the the struggling new nation, just as they are to the region today.
