Major Stephen Long (1784-1864)

Major Stephen Long’s 1819-1820 expedition developed out of U.S. concerns over British interest in the northern Plains. His expedition eventually was redirected to map the central Plains to the Rocky Mountains. Long was the first Army explorer to include professional scientists on his survey team. He also was the first to use a steamboat for exploration purposes.
