1 DR. BOTHNER: Could you say a word about the size of the sediment 



2 traps you used? 



3 DR. AYERS: They were .05 square meters. I will show you a 



4 picture of one here. I don't have a--here you go, Mike. 



5 DR. BOTHNER: It has got a height and width ratio of about two and 



6 two below [sentence unclear]? 



7 DR. AYERS: Yes. 



8 DR. BOTHNER: I see. That would keep material in the trap once it 



9 fell in. 



10 DR. AYERS: That was what we were trying to do. EG&G designed 



11 these things. They know more about that than I do. 



12 DR. BOTHNER: I would like to point out that that high flux that 



13 you obtained in the canyon of about a kilogram per meter per day is only 



14 a factor of five times higher than we found in some of the canyons to 



15 the north, so I don't think you have to evoke the canyon falling in on 



16 the traps. 



17 DR. AYERS: I was being facetious. 



18 DR. BOTHNER: I know you were, but I was surprised it was the same 



19 order of magnitude of what we found. 



20 DR. AYERS: That is kind of interesting, yes. Does anybody else 



21 have any questions? 



22 (No response.) 



23 DR. AURAND: If there aren't any more questions for Bob, we will 



24 go ahead and continue on with the schedule.

26 ROUNOTABLE DISCUSSION 



27 



28 There was some discussion yesterday about what we needed or 



29 intended to do for the remaining two days. I thought about that a 



30 little last night, while I was watching the end of "Heartbreak Ridge." 



31 I don't know if there is any connection there. 



32 One of the things that we were trying to do when we planned all 



33 this was to minimize MMS' involvement, but I think it is probably a good 



34 time for myself and Jim to make a few comments about what we thought we
