Show Record made a subsequent trip on the best from Lees Ferry up the river 1856 five or six miles. We had no trouble on that trip. This boat was on the Colorado River at lee's Ferry the last I heard of it. I think it is still there but do not know whether it is in opera-tion. The last time I was there was in 1921. We found a trail leading up to the mesa from Lee's Ferry and the largest amount of supplies used by the party working on the lower part of the 1857 reservoir site was taken to them by this pack train. We had three principal parties working on the river. One party. in charge of Mr. Chenoewith, was to descend the river from Green Riv- 1858 er, Utah, as far as possible. Mr. Trimble was in charge of another party that started at Bluff and worked down the San Juan River to the Colorado River and thence down the Colorado River for per-haps twenty miles. I saw Mr. Trimble opposite the mouth of Copper 1859 Canyon, going there overland by horseback from Bluff, which town we had reached by automobile from Green River, Utah. This overland trip consumed about two days. I spent one day with Mr. 1960 Trimble and saw his boat, a skiff, on the San Juan River, He was mapping the country and was taking all the topography below the thirty- nine hundred foot contour. I checked up the accuracy of 1962 his work. After visiting Mr. Trimble I went back to Green River, Utah, overland, as I had come. Then I visited some other field parties and later went back to Lee's Ferry. Mr. Fowler's party was also working on the lover Colorado River. When I was saw him he was in the vicinity of Warm Greek, to which point I rode from 1865 Lees Ferry on horseback. A contour map is a map on which the lines are supposed to represent equal elevations or heights above sea level throughout its whole course. We determined enough eleva-tions throughout the are to enable a man to sketch those contours as near as he can on the scale of the rap. The straight brown lines appearing inside the blue lines of sheet A of Exhibit 10 represent five- foot contours of the water surface at the time the survey was made.
