Fort Keogh

Fort Keogh is a former military complex along the Yellowstone River in Miles City that now houses USDA research facilities including laboratories and grazing lands. The site spans thousands of acres where scientists study livestock breeding, animal health, and rangeland management.

Colonel Nelson Miles established the fort in 1876 following the Battle of Little Bighorn to monitor Native American movements toward Canada. After World War I, it became the largest remount station for military horses before being converted into a research center.

The fort transformed from a military installation to the largest remount station during World War I, supplying horses for military operations worldwide.

The site is accessible by car and offers areas to explore both the historical and modern research facilities. Visitors should wear appropriate clothing for variable weather and be prepared for distances across the grounds.

A record-size snowflake was documented here in 1887, making it a notable spot in meteorological history. This unusual weather event from over a century ago remains one of the most remarkable natural observations recorded at the location.
