Bears Tooth is an 11,920-foot mountain spire in Montana’s Beartooth Mountains, in the Absaroka-Beartooth Wilderness within Custer National Forest near Beartooth Mountain, and it can be seen from the Beartooth Highway. Beyond its striking, sharp form, it is important for the way it shaped regional place names. The Crow name for the spire, Na Piet Say, means bears tooth, and that name was adopted for nearby landmarks and ultimately for the Beartooth Mountains themselves.
