One of the most famous sandstone buttes in America, Pompeys Pillar National Monument bears the only remaining physical inscriptional evidence of the Lewis & Clark Expedition. On the face of the 150 ft rock, Captain William Clark carved his name and the date, July 25th, 1806, during his return to the United States through the beautiful Yellowstone Valley. The rock and signature appears the same today as it did 200 years ago! Captain Clark named the Pillar, "Pompy's Tower" in honor of Sacagawea's son Jean Baptiste Charbonneau, whom he had nicknamed "Pomp."
