I mean to REALLY prove. This does not mean that isn't a good idea.</DIV> <DIV> </DIV> <DIV>It is something all together different to do like I have recently done, hypothesize that Beehive is having "monthly" long peak intervals during the Moon's 1st Quarter phase, as published for 2004 in GOSA Transactions volume IX and earlier discussed to some extent in volume IV.</DIV> <DIV> </DIV> <DIV>I've long been puzzled by the rather vigorous denial of any relationship by Dr. D. E. White (late of the USGS) and others, given that White himself showed an apparent relationship between lunar tides and an erupting well at Steamboat Springs, Nevada (in USGS PP458-C).</DIV> <DIV> </DIV> <DIV>Dr. John Rinehart was long a proponent of tidal influences, not only on hot springs but numerous other things as well. He published his thoughts in a number of works. Shortly before his death, Rinehart produced a draft manuscript dated June 2001 that is titled: "Lunar Influence on Geophysics and Archaeology -- Studies of long period cycles." John's widow, Marion, sent me a copy. I'm certainly not going to let go of it, nor will I dupe it (since it is 246 pages). I don't think Mrs. Rinehart is on-line, so privately I will send her mailing address to Mr. Kronholm. Perhaps another copy of the manuscript is available.</DIV> <DIV> </DIV> <DIV>Anyhow, info is out there. Scattered and mostly very tentative, I think. So go for it.</DIV> <DIV> </DIV> <DIV>Scott Bryan</DIV></BODY></HTML>
