Show Record In response to interrogatories propounded by the Special Master, Mr. Freeman testified as follows: I would say roughly that we were about twelve days going from Lee's Ferry up to Hall's Crossing, averaging slightly better 2583 than ten miles a day. While we were waiting at Hall's Crossing before returning down the river, I took one boat and four of the party ten miles upstream through Bull Frog Rapid and on up to a creek where there were some interesting cliff dwellings, passing an old abandoned dredge on that trip. Resuming his direct examination Mr. Freeman testified as follows: On the trip down from Hall's Crossing we encountered occasional groundings on sand bars; perhaps touched a few more sand bars than on the up trip, our boats being more heavily loaded; but on the down trip we met with nothing like the continuous delays and troubles that we encountered from currents, rocks and 2589 other difficulties that we encountered on the up trip. There were only five of us on the down trip and we went down in two units with two boats lashed together, as on the up trip. Going down we spent something like a week on the river, making stops at the San Juan River, making surveys, stopping at Rainbow Bridge and also at Warm Creek, where we crawled out on to the mesa and located one or two points on Father Escalante's route. We also 2590 stopped at Hole- in- the- Rock. There is a great deal more sand and silt below the San Juan River, which brings in a great amount of it. A sand wave is a wave very much sharper than the ordinary wave and the water contains possibly as great as fifteen to twenty per cent by weight of sediment. On our trip there were evidences of a sand wave condition the morning we had the heavy flood above Rainbow Creek, but nothing like I have seen on the lower river be 2591 low Grand Canyon or such as one would see on the San Juan. The river raised four or five feet that night and I noticed in wading the rapid next morning that there was a more broken condition of |
