Show Record We used the big boats for the transportation of our 4027 supplies. Pages 17 to 29, inclusive, of Exhibit 10, are my work. That is the survey of the upper end of the river. The profile maps, 58 and 59, are also my work. 4033 Raymond C. Seitz testified on cross examination as follows: All told, I have spent about 7 months on the Colorado 4034 River. Below Castle Creek I have spent about two months on the Colorado River, from the latter part of October to the first part of December. I terminated my first Colorado River experience in Utah at a point near Castle Creek. From there we went down to Moab 4036 and cached our equipment there, which consisted of two boats and ordinary camp outfit. We had a wagon come up and we were able to load everything on the wagon and take it to Moab. The road follows the river. I had no maps or surveys of the river before I came down.

That department deals with the survey of rivers. 4038 These profile sheets in Exhibit 10 are intended to give a picture of the slope of the water surface. The word gradient is equivalent of slope. The profile sheets are not drawn to a scale. The vertical scale is ordinarily somewhat exaggerated on the profile in order to show more clearly the differences on slope. A slope, for instance, of one on two feet to the mile would not be visible to the naked eye on the surface of the earth and would show practically as a straight line. For that reason these profiles are reports on an exaggerated |
