Show Herman Stabler testified 121 : I am ( chief clilef ) of the ( Conserva Conserva- Conserva ) tion Branch of the Geological Survey . ( R . 4036 , Vol . 22 . ) 1 have crossed the San Juan , Green and Colorado rivers at different places and I have made a boat trip from ( Hall's Halls ) Crossing to Lees Ferry . ( R . 4041 , Vol . 22 . ) On this boat trip , made in early September , 1922 , ( I 1 ) think that we stuck several times ; I think every time we were on the river . ( R . 4054 , Vol . 22 . ) At one place only , bed rock extended clear across the river and our boat scraped in the best channel that we could find where the water must have been less than a foot deep for a distance of 50 feet or more . ( R . 4055 , Vol . 22 . ) We would often run into sand bars unawares and once were stuck for several hours . We were traveling down the river at a little too great a speed and went pretty well up on the bar . In a silty river like this there is a tendency for a bar to form in the middle of the stream with a channel on either side and it is quite hard when coming downstream with the muddy water to tell ( which ivhich ) channel to take . We had four open row boats 18 feet long , with a ( 4-foot 4foot ) beam and a draftof 6 to 8 inches . ( R . 4059-60 , Vol , 22 . ) Selden Spencer Nye testified : I am with the U . S . G . S . and on September 26 , 1926 , ( vith with ) another man made a boat trip from Green River , Utah , to the mouth of the Green in a ( 16-foot 16foot ) boat having an Evinrude motor , our purpose being to map the geology of the canyon . In the first 21 miles we had a great deal of difficulty because of the rapids , and at the mouth of the San Rafael were compelled to wade and drag the boat over gravel because it was so difficult to find a continuous channel at that point ( , . ) Thence down to the mouth of the Green there was only one riffle , which ( wasn't wasnt ) bad , but we had trouble avoiding sand bars and we were in the water a good deal searching for a continuous channel . From the mouth of the Green up to Moab , because of a rain , the water was deeper and we just had enough power to make it up through the Slide . We did not ( en- en ) counter any sand bars until we got upstream 15 or 20 miles above the junction and we had the most trouble at a point a mile below the Moab bridge . Our boat drew about a foot and a half of water . ( R . 4181-6 , Vol . 24 . ) Neither I nor my companion had ever been on the rivers before and had no knowledge as to the location of channels . We quite frequently went ashore . We could not see where the channel was every time and were quite often |
