Stephen Harriman Long – Exploring the Great Plains
Stephen Harriman Long, a name synonymous with early American exploration and engineering, left an indelible mark on the landscape and understanding of the Great Plains. A multifaceted individual, Long excelled as a military officer, an accomplished engineer, and a pioneering explorer. His most significant contribution to American history lies in leading what became known as Long’s Expedition, a venture commissioned to map and document the vast, largely uncharted territory between the Mississippi River and the imposing Rocky Mountains.
Born on December 30, 1784, in Hopkinton, New Hampshire, Stephen Harriman Long was the son of Moses and Lucy (Harriman) Long. His early life instilled in him a thirst for knowledge and a dedication to academic pursuits. He pursued higher education at Dartmouth College, where he demonstrated exceptional intellectual capabilities. Long earned his bachelor’s degree in 1809 and continued his studies at the same institution, ultimately achieving a master’s degree in 1812. This strong academic foundation would prove invaluable in his future endeavors, providing him with the analytical skills and scientific understanding necessary for exploration and engineering.
Long’s career path took a significant turn when he was commissioned as a lieutenant of engineers in the United States Army in 1814. His mathematical prowess and engineering aptitude quickly distinguished him. From 1815 to 1818, he served as a mathematics professor at the prestigious military academy at West Point, shaping the minds of future military leaders. This role further honed his skills in instruction, observation, and organization, qualities that would serve him well in his later expeditions.
April 1819 marked a pivotal moment in Stephen Harriman Long’s career. He was brevetted to the rank of major and entrusted with a monumental task: leading an expedition to explore the vast territory stretching from the Mississippi River to the Rocky Mountains. This assignment reflected the growing national interest in the West and the desire to understand its resources, geography, and potential for settlement. The Stephen Harriman Long expedition was intended to provide vital information for the expanding nation.
Just prior to receiving this significant appointment, Long married Martha Hodgkins of Philadelphia, Pennsylvania, on March 3, 1819. This personal milestone coincided with the commencement of his most ambitious professional undertaking. The expedition would test his leadership, resilience, and scientific acumen, shaping his legacy as a key figure in the exploration of the American West.
The expedition, formally known as the Scientific Expedition to the Rocky Mountains, was a complex undertaking, involving a team of scientists, artists, and military personnel. Their mission was to survey the land, document its flora and fauna, map its rivers and mountains, and establish contact with the Native American tribes inhabiting the region. The journey was fraught with challenges, including harsh weather conditions, difficult terrain, and encounters with unfamiliar cultures.
The Stephen Harriman Long expedition followed the Platte River, meticulously documenting the landscape and its inhabitants. The team collected specimens of plants and animals, sketched the terrain, and recorded their observations in detailed journals. Their accounts provide invaluable insights into the Great Plains during the early 19th century, capturing a snapshot of a rapidly changing environment.
However, the expedition is also remembered for its controversial assessment of the Great Plains. Based on their observations, Long and his team concluded that much of the region was unsuitable for agriculture and settlement, labeling it the "Great American Desert." This assessment, while based on the limited understanding of the region’s potential at the time, had a lasting impact on perceptions of the Great Plains, contributing to the delayed settlement of the area. Stephen Harriman Long made a lasting impact on how the American West was viewed.
Despite the "Great American Desert" misnomer, the Stephen Harriman Long expedition produced a wealth of valuable scientific data and geographical information. The maps and journals created by the expedition provided the most accurate depiction of the region to date, contributing significantly to the understanding of the American West. The expedition also played a crucial role in opening up the region to further exploration and development.
Following his return from the expedition, Stephen Harriman Long continued to serve the nation in various capacities. He dedicated several years to surveying and constructing the Baltimore & Ohio Railroad, one of the earliest and most important railroads in the United States. His engineering expertise was instrumental in overcoming the numerous challenges involved in building a railroad across challenging terrain.
Long’s contributions extended beyond railroad construction. He was also an inventor, securing several patents for improvements to steam locomotives. His innovations helped to advance the technology of rail transportation, contributing to the growth and expansion of the American economy. Stephen Harriman Long was not only an explorer, but also an innovator.
In 1838, when the United States Topographical Engineers’ Corps was organized, Major Long was appointed to a prominent position within the organization. This appointment recognized his expertise in surveying, mapping, and engineering, and further solidified his reputation as a leading figure in the field. He served with distinction in this corps for many years, contributing to the development of infrastructure and the expansion of the nation’s transportation network.
After a long and distinguished career in the military and engineering, Stephen Harriman Long retired from the army. He spent his final years in Alton, Illinois, where he passed away on September 4, 1864. His legacy as an explorer, engineer, and military officer endures, reminding us of the individuals who shaped our understanding of the American West. The work of Stephen Harriman Long continues to be studied by historians and geographers.
Stephen Harriman Long’s impact on the United States is undeniable. His exploration of the Great Plains, while not without its misinterpretations, provided invaluable information about a region that would become vital to the nation’s agricultural and economic future. His engineering contributions, particularly in the development of railroads, helped to connect the country and facilitate westward expansion. His dedication to public service and his commitment to scientific inquiry serve as an inspiration to future generations of explorers, engineers, and leaders.
