In Yellowstone, a nice example (not often active from all vents) is Oval Spring, which might contain as many as four separate geysers that all show up within the one crater.</DIV> <DIV> </DIV> <DIV>But please note that I was simply speculating about the geyser at Black Sand. I have not taken the "liberty" to trek out to the site. Per the USGS thermal Map, there are at least four (maybe five -- my copy is a touch blurry) vents mapped there, and _all_ of them are active to some extent.</DIV> <DIV> </DIV> <DIV>Scott Bryan</DIV></FONT><BR><BR><BR><DIV><FONT style="color: black; font: normal 10pt ARIAL, SAN-SERIF;"><HR style="MARGIN-TOP: 10px">See what's free at <A title="http://www.aol.com?ncid=AOLAOF00020000000503" href="http://www.aol.com?ncid=AOLAOF00020000000503" target="_blank">AOL.com</A>. </FONT></DIV></BODY></HTML>
