The Lost Journal
of John Colton Sumner BY O. DOCK MARSTON
M .AY 24, 1869, TEN MEN embarked at Green River, Wyoming, projecting a cruise through the canyons of the Green and Colorado rivers. William H. Ashley, Denis Julien, William L. Manly, and H. M. Hook had boated sections of the Green River to total the course from the point of the 1869 embarkation to the confluence with the Colorado. Julien must be credited with thirty miles of the fast water of the Colorado Mr. Marston, an authority on the river-running of the Colorado and its tributaries, has spent years not only running the river but researching the history of river navigation.
