On this date the members of the Lewis and Clark Expedition spotted the first buffalo they had ever seen, according to journal entries from the date.. It was near present day Kansas City. 

The American bison, often referred to as the buffalo, has a deep and storied history that stretches back thousands of years. The earliest bison appeared in North America during the Pleistocene Epoch, approximately 240,000 years ago. These ancient bison were significantly larger than their modern descendants. Over time, the species evolved and adapted to the changing climates and environments of North America, leading to the development of the modern bison (Latin name Bison bison), which we are familiar with today. Fossil evidence indicates that bison were once widespread across the continent, roaming from Alaska to Mexico and from coast to coast. They thrived in the grasslands, prairies, and plains, playing a crucial role in the ecosystem by grazing and aerating the soil.

By the time the Lewis and Clark Expedition embarked on their journey in 1804, the American bison was a well-established and vital part of the Great Plains ecosystem. The expedition’s sighting of the first bison came on this date. Although the men in the Corps of Discovery were already familiar with the species, this marked their first time encountering one in the flesh. At the time herds of bison were so immense that they stretched as far as the eye could see, a testament to the bison’s prominence in the landscape. For the Native American tribes of the region, the bison was not only a source of sustenance but also a central figure in their culture and spirituality. The sighting by Lewis and Clark underscored the importance of the bison in the natural and cultural tapestry of early 19th-century America.

In the decades following the Lewis and Clark Expedition, the American bison faced severe threats from overhunting and habitat loss. By the late 19th century, the population had plummeted from an estimated 30-60 million to fewer than 1,000 individuals. This dramatic decline was driven primarily by the expansion of European settlers, who hunted bison for their hides and meat and to undermine the livelihood of Native American tribes. Conservation efforts in the early 20th century, led by figures like Theodore Roosevelt and organizations such as the American Bison Society, played a crucial role in saving the species from extinction. Today, thanks to these efforts, the bison population has rebounded to approximately 500,000, with individuals residing in protected areas, national parks, and private lands. The bison has not only become a symbol of American wildlife conservation but also a significant cultural icon, representing the resilience and enduring legacy of North America’s natural heritage.
