Show o ( 1008 100S ) ( Greek Creek ) ) ( he lie ) thinks was done by ( Trimble Trinible ) , the balance * being done by Leech and ( Hayclen Hayden ) who were ( mem mem- mem ) bers of his [ ( Fowler's Fowlers ) ] party . ( R . 3968-3970 . ) The profiles shown on Sheet 52 indicate the fall of the river , giving the horizontal and vertical scales indicated on the plat , and from the starting point , zero , marked at Lees Ferry , the first one [ profile ] runs up a distance of ten miles , which means ten miles above Lees Ferry . The figure 3115 , over on the ( right-hand righthand ) corner , represents 3,115 feet above sea level . Lees Ferry is 3,120 feet above sea level ( R . 3970 ) ; 3,120 feet represents the level of the ( sur- sur ) face of the water as it was on the day he saw it and would vary according to whether the river was high or low . The figure 3125 , appearing on the map , ( rep- rep ) resents a point 3,125 feet above sea level , that is reached at about mile 3 , and that is the water level on the day on which he surveyed it . If there had been a sudden flood , or ( a a- a ) higher stage of water , the elevation above sea level at that point would have been higher . ( R . 3971-3972 . ) A river continually changing , as does this river [ the Colorado ] , the elevation of the surface of the water above sea level would depend entirely on the date on which the survey was made . It would have to be used in conjunction with the gage readings , and he believes they attempted to eliminate any sudden , abnormal stage of the river . ( R . 3972-3973 . ) How does that represent any permanent condition upon which one can base operations subsequently ? That |
