William Emory was never well-known but his work is among the best of the soldier-explorers. A graduate of West Point, he earned the respect of his troops as a fighting officer in two major wars. He also was an excellent scientist and scholar, working in the Southwest both during and after the Mexican War (1846-1848). His maps and expedition reports helped create the current Mexico-U.S. boundary.

#EcoTrekUSA 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.
