In May of 1869, eleven men embarked on a journey of exploration and discovery. 98 days later six of them arrived 1000 miles away after navigating the Green and Colorado Rivers to the end of Grand Canyon. The journals and writings of the expedition leader, John Wesley Powell have been extensively published but here, for the first time, are the newly transcribed, unabridged journals and letters of some of the other members of the group. Author Ghiglieri has used his extensive river running experience to introduce the whole group and their exploits of courage and endurance.
