To this end, Ian Campbell organized the river trip, this being the best manner in which to study the rocks of the inner gorge. In addition to Maxson, he added Robert P. Sharp, who was working on his Ph.D thesis at Harvard University; John T. ¨Jack¨ Stark of Northwestern University, and Edwin McKee, who joined the trip at the Bass Trail. The three boatmen were Frank B. Dodge, rowing the Fairchild, Owen R. Clark in the Collier, and Merril Spencer at the oars of the Eliel.
The trip launched on October 11, 1937 at Lees Ferry, taking out at Pierces Ferry on November 25, covering a distance of some 280 river miles. Sharp recorded his findings in detail in both written and photographic format. The photographs in the three albums are referenced in his three field notebooks, which are housed in the Carnegie-Cal Tech Manuscript collection.
The Carnegie-Cal Tech trip is perhaps best known as the trip which was passed by Haldane ¨Buzz¨ Holmstrom on his remarkable solo voyage through the Grand Canyon. Also of note is that the Carnegie-Cal Tech group was the last to see two of the largest and most intimidating rapids on the Colorado: Separation and Lava Cliff. By the next year, both had been submerged by the rising waters of Lake Mead.
