He’s cute, he’s sleepy, and he’s in your pocket. He’s Pompï¿½the napping baby on the new Sacagawea dollar coin. Learn all about his amazing life in this e-book for kids. In 1805, Pomp and his mother Sacagawea traveled across the western United States on the Lewis and Clark Expedition. But that was only the beginning of his adventures. As an adult, Pomp toured Europe with royalty, blazed new trails as a mountain man, survived a bear attack as a U.S. Army scout, and became one of the first Americans to catch “gold fever” during the California Gold Rush.
