Show 169 maps that they were using-- they were using the mileage below Greenriver, without carrying along a continuous survey; so that there may be a mile or so difference in what they are describing and what we saw. On Plate 26 is the first Anvil bar and riffle, 100 miles above the mouth; and the comparison is shown between this in 1909 and 1928. And at the mouth of the San Rafael, 94.9 miles above the mouth of the Green River, is shown a survey of the conditions that were found in 1928. Also on Plate 29 is shown the comparison between the bar as it was in 1909 and as it was on March 2, 1928, which was sketched from a photograph taken on the right bank, and referred to as 33- A in the Plates or photographs, and the survey of 1928. this particular bar is at the mouth of the San Rafael, and it is formed by sediment carried by the San Rafael into the channel of the Green River, and maintains itself against the various floods that come down, and in all probability is one of the most shifting bars that we have in the river. By Mr. Farnsworth: Q What do you call that bar? A That is the San Rafael bar. By Mr. Blackmar: Q Well, the difference between the bar as it was on March 2, 1928, and when you surveyed is very marked, is it not? A Yes. From the appearances, it is a constantly shifting bar. 2130 |
