Mule Deer Foundation Idaho

This encounter marked the first documented scientific description of the mule deer by Euro-American explorers. While Indigenous peoples across the American West had hunted and lived alongside mule deer for centuries, the Lewis and Clark journals provided the first written account of the species for the expanding field of American zoology. This documentation description would continue throughout the journey as more of these creatures were brought in, and Lewis would later start referring to them as mule deer. That’s how they came to be known by the name we know them by today.
