As Lewis and Clark led their Corps of Discovery to the Pacific Ocean, Lieutenant Zebulon Pike led an expedition to find the source of the Mississippi River. In 1806–07, Pike mapped the American Southwest and studied the Native Americans in the region. Students will learn about Pikes Peak, Pike’s capture by the Spaniards, his trip to Santa Fe, and his journey on El Camino Real. The book includes maps from Pike’s journal that is now housed in the National Archives.
