Show Record the river straightens and many times you will have a crossing from one bend to the other, with no channel, where the channel will spread out like that, sand, I can sum it up by saying that generally throughout this trip we had trouble with sand bars. Where there is a crossing bar the channel crosses from 2335 the opposite side. Crossing bars as a rule are formed by side canyons through which there has at come time swept a big flood, 2336 which has caused the bar. Where the river turns there is in-variably a bar inside the band, and any channel at such places will be on the outside of the bend. On the 1921 trip I saw no other boats on the San Juan River beside ours. 2340 After reaching the mouth of the San Juan we continued on down to Lee's Ferry, Mr. Trimble's survey ending at West Canyon on the east side of the river. In going down the San Juan we had two boats, but from the mouth of the San Juan down the Colo-rado we had three boats in our party. I took our cook and our recorder, Mr. Allen, down to Lee's Ferry, went from there to 2341 Flagstaff, and brought a cook and rod man back. We left the mouth of San Juan River about October 6. Our difficulties in going down the river to Lee's Ferry consisted of the usual sand bars, the water being very low at that time, and we ran on to a few sand bars; that was about all our trouble. Our greatest difficulty was at the mouth of Navajo Creek, which was just over the line from Utah. We came back up the river with the new cook and rod man in a motor boat, approximately twenty- five feet long and six feet wide, with a draft, as loaded, of probably eighteen inches. There were six or seven people on the boat and I also had my row boat. There was room on the boat for more people, but you could not carry any more comfortably. Mr. Marrs was in charge 2343 of the motor boat. I think we were about four days making the upstream trip. Our most serious problem was encountered just be-low Last Chance Creek, where six of us got out in the river and waded back and forth to find a channel, and we finally got the boat |
