Beaverhead Rock is a rock feature identified in 1805 by Sacagawea, during the Lewis and Clark Expedition, as a landmark not distant from the summer retreat of her nation. According to the Journal of Lewis:
The Indian woman recognized the point of a high plain to our right which she informed us was not very distant from the summer retreat of her nation on a river beyond the mountains which runs to the west. This hill she says her nation calls the Beaver's Head, from a conceived resemblance of its figure to the head of that animal...as it is now all important with us to meet with those people as soon as possible I determined to proceed tomorrow with a small party...and pass the mountains to the Columbia; and down that river until I found the Indians...without horses we shall be obliged to leave a great part of our stores...
