It's a whistling sound <BR>that can last up to 30 seconds--usually between the hours of dawn and <BR>10 a.m. The book claims early trappers and Native Americans also knew <BR>about it (no record of how this was documented listed).</FONT></BLOCKQUOTE></DIV> <DIV> </DIV> <DIV>Pat:</DIV> <DIV> </DIV> <DIV>How nice that you brought this up, as I just days ago encountered my memo to the NPS about my own experience... As many others know, this is the "Lake Sound" that goes by a great many names, and has been documented very often. I tended to disbelieve -- until I experienced it myself.</DIV> <DIV> </DIV> <DIV>I was camped (legally) at the old patrol cabin site at Shoshone Geyser Basin -- alone, unfortunately -- and I remember it vividly. The time was in the evening. A ferocious thunderstorm with really scarey lightning had recently passed by, and to the east the clouds with probably the biggest (s'cuse the thought) pendulous mammary cloud bottoms I've ever seen were tinged with vivid red-gold from the setting sun. That in itself was a strange sight. And while I was standing in the North Group somewhere near Knobby Geyser, I heard it coming. Yes, heard it _coming_ toward me. From the lake. A deep moaning sound that I can best likened to a French horn blowing a steady low note. It was freaky, until I realized what it was. Then it was fantastic. It honestly passed overhead and faded into the west. And it was over too soon. Start to finish, probably something between 5 and 10 seconds. A few minutes later it repeated, and then again and again three or four progressively fainter times.</DIV> <DIV> </DIV> <DIV>Most decidedly, it has nothing whatsoever to do with hot springs of any kind. I guess it must be some kind of resonance between clouds and a broad, long open fetch of lake. At least in "my" case.</DIV> <DIV> </DIV> <DIV>Scott Bryan</DIV></BODY></HTML>
