The Beaverhead Rock, or just The Beaverhead is a rock formation overlooking the Beaverhead River in southwestern Montana. Today, it is on SH 14 twelve miles south of Twin Bridges, Montana.

According to the Journal of Meriwether Lewis, this rock was identified in 1805 by Sacagawea during the Lewis and Clark expedition, as a landmark not far from the summer retreat of her nation of people.

During the cross continent trek by Lewis and Clark, the expedition passed by this limestone outcrop, but this monolith served as an important landmark and meeting place, long before their passage. The indigenous natives known as the Shoshone people came to this area each year during the summer.

Sacagawea, who was with the Corps of Discovery had told Lewis and Clark about this landmark and they had been looking for it for some time prior to their arrival here on the fifth of August, 1805. It was expected that the Shoshone would be here, from whom they hoped to obtain horses. The horses would aid them in crossing the Rocky Mountains prior to the winter set in.

Upon their arrival at Beaverhead, the Corps of Discovery did find the Shoshone, whose chief, by amazing coincidence, was the brother of Sacagawea.

Then, as early as the middle of the 1800's this ancient landmark and pathway that had existed here for so very long, had now become the landmark on the primary travel route used by ranchers and their cattle drives. When by 1860, gold had been discovered, freight wagons used this same ancient trail and landmark, now called the Montana-Utah road to bring supplies to the prospectors and soon after them, came the settlers. All during the 1800's, this is that roadway which was the most heavily traveled in the entire state of Montana.

In 1863, the Point of Rocks stage station was open which included a hotel, saloon, and post office and this station remained open until 1885. Roads form all over Montana converged here, those from Helena as well as from the Big Hole valley. Then, the railroad began to pass through the area, taking over the clientele of the stage stop and which finally made the Point of Rocks station obsolete.

However, during the years of 1863 to 1885, the Point of Rocks Stage Station was the go to place for anyone to or from Helena, Virginia City, Bannack and many other places.
