The ninth book in the bestselling series tells the story of John Wesley Powell, the one-armed geologist who explored the Grand Canyon John Wesley Powell (1834–1902) always had the spirit of adventure in him. As a young man, he traveled all over the United States exploring. When the Civil War began, Powell went to fight for the Union, and even after he lost most of his right arm, he continued to fight until the war was over. He then embarked on the 1869 Powell Geographic Expedition, which became the first official US government-sponsored passage through the Grand Canyon. Over the course of three months, the explorers lost their boats and supplies, nearly drowned, and were in peril on multiple occasions. However, they made it through, and Powell would come to be known as one of the most epic explorers in history! Equal parts gruesome and hilarious, this latest installment in the bestselling series takes readers on an action-packed adventure through American history.
