in his journal as "a wonderful canyon four thousand feet deep. Everyone (in the party) admitted that he never before saw anything to match or equal this astonishing natural curiosity." A U.S. War Department expedition led by Lt. Joseph Ives was launched in 1857 to investigate the area's potential for natural resources, to find railroad routes to the west coast, and assess the feasibility of an up-river navigation route from the Gulf of California. The group traveled in a stern wheeler steamboat named Explorer. After two months and 350 miles (560 km) of difficult navigation, his party reached Black Canyon some two months after George Johnson. In the process, the Explorer struck a rock and was abandoned. The group later traveled eastwards along the South Rim of the Grand Canyon. A man of his time, Ives discounted his own impressions on the beauty of the canyon and declared it and the surrounding area as "altogether valueless", remarking that his expedition would be "the last party of whites to visit this profitless locality". Attached to Ives' expedition was geologist John Strong Newberry who had a very different impression of the canyon. After returning, Newberry convinced fellow geologist John Wesley Powell that a boat run through the Grand Canyon to complete the survey would be worth the risk. Powell was a major in the United States Army and was a veteran of the American Civil War, a conflict that cost him his right forearm in the Battle of Shiloh. More than a decade after the Ives Expedition and with help from the Smithsonian Institution, Powell led the first of the Powell Expeditions to explore the region and document its scientific offerings. On May 24, 1869, the group of nine men set out from Green River Station in Wyoming down the Colorado River and through the Grand Canyon. This first expedition was poorly funded and consequently no photographer or graphic artist was included. While in the Canyon of Lodore one of the group's four boats capsized, spilling most of their food and much of their scientific equipment into the river. This shortened the expedition to one hundred days. Tired of being constantly cold, wet and hungry and not knowing they had already passed the worst rapids, three of Powell's men climbed out of the canyon in what is now called Separation Canyon. Once out of the canyon, all three were reportedly killed by
