∼John Colton Sumner was a noted western frontiersman. He served as a guide for Bayard Taylor during his 1866 expedition to Colorado and then did the same for Major John Wesley Powell when he came to Colorado on his 1867 and 1868 expeditions. Jack, as he was called, then served as Major Powell's lead guide on his noted river expedition of the Green, Grand, and Colorado rivers including the first recorded descent of the entire lengths of the Grand Canyon in 1869. Major Powell left that expedition at the Virgin River but Jack and Andy Hall continued down river with George Bradley and Billy Hawkins after Powell and his brother left. Jack and Andy continued on after Bradley and Hawkins left the river and eventually made their way to the mouth the Rio Colorado as it empties into the Gulf of California; making them the first to make the continuous river journey from Green River, WY to the Colorado river's mouth in Mexico.
