POMPEY'S PILLAR, 241.2 m. (R), is an isolated rock 200 feet high on the south bank of the Yellowstone River. Clark climbed it, July 25, 1806, and carved his name on it. He named the rock in honor of little Pomp, son of Charbonneau and Sacajawea, chief 
guides and interpreters of the Lewis and Clark expedition. It had long been used by the Indians as a lookout and as a point from which to send up smoke signals.- Montana: A State Guide Book, 1939, Tour 1, pg. 193.
