Resembling the head of a swimming beaver, this natural landmark is listed in the National Register of Historic Places. The site may be viewed and photographed from a distance, but is not directly accessible. Sacajawea recognized this huge landmark resembling the head of a swimming beaver while traveling with the Lewis and Clark expedition in 1805.
The expedition was traveling the headwaters of the Missouri, now known as Three Forks. Sacajawea recognized a point on a high plain, Beaverhead Rock, as being near the summer retreat of her own people, the Shoshone.
The sighting gave the expedition hope that they may be able to find Native peoples from which to acquire horses for their trip across the mountains to the Pacific Ocean. The site is 4949 feet in elevation and is 71 acres in size. The rock itself is located 14 miles south of Twin Bridges on Montana 41 in Montana.
