Powell's 1869 expedition was the first successful attempt to map the Colorado River. This volume assembles the explorers' journals, accounts, and letters into a compelling day-by-day narrative.
When geologist Powell and his party of explorers first assayed the Colorado in 1869, it was North America's longest stretch of uncharted river. This is the story of that three-month, thousand-mile excursion, told in the words of the men who negotiated and mapped the river, through their journals, accounts, and letters. Black-and-white illustrations.
