Thanks for the answers, everybody! There is SO much to learn from people on this list ...<br><br>What we observed was more "mud pot" than "mud thumper"; there was mud, and no obvious acoustic component -- although New Imperial was so active that it was hard to hear much else. Still, it was compatible with what everyone has described. Incidentally, the biggest burst we saw from New Imperial itself was very impressive indeed -- if most were hitting the nominal 40 feet or so mentioned in GOY4 (and consistent with some crude triangulation we did on site), this one may well have (very briefly) reached 75 feet or even greater. I sure wish we'd had a portable theodolite along!<br> <br>-- Bill.<br><br><div class="gmail_quote">On Wed, Oct 20, 2010 at 11:05 AM, Stephen Eide <span dir="ltr"><<a href="mailto:stepheneide@cableone.net">stepheneide@cableone.net</a>></span> wrote:<br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> <div>Hello Bill, </div> <div> </div> <div>I know there as been some mud pots on the west side of Imperial for at least the last decade. I usually end up visiting the area late in the summer when they are more like mud thumpers, not much mud, just a deep thumping noise maker. I seem to remember reading somewhere the mud pots have been there for a lot longer than that. </div> <div> </div><font color="#888888"> <div>Stephen Eide<br><br></div></font><div><div></div><div class="h5"> <div class="gmail_quote">On Tue, Oct 19, 2010 at 1:14 PM, Bill Johnson <span dir="ltr"><<a href="mailto:mwjohnson@lanl.gov" target="_blank">mwjohnson@lanl.gov</a>></span> wrote:<br> <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0px 0px 0px 0.8ex; padding-left: 1ex;">I feel the need to apologize twice for this inquiry. First, I should have made it six weeks ago, when we were at the park and could act on any followup. Second, I may be the only person on the mailing list who doesn't already know the answer! But anyway:<br> <br>When my wife and I hiked out to Imperial Geyser (OK, *New* Imperial Geyser) last month, we noticed what looked like the beginnings of a mud pot very near the trail on the "upstream" side of the old Imperial crater. I've never seen anything about mud pots at or near Imperial in any of the sources I've consulted (certainly not an exhaustive list) and have been wondering whether this is a new feature. Anybody got anything on it? I can post a not-very-impressive photograph if there's interest.<br> <br>-- Bill J.<br><br>_______________________________________________<br>Geysers mailing list<br><a href="mailto:Geysers@lists.wallawalla.edu" target="_blank">Geysers@lists.wallawalla.edu</a><br><a href="https://lists.wallawalla.edu/mailman/listinfo/geysers" target="_blank">https://lists.wallawalla.edu/mailman/listinfo/geysers</a><br> </blockquote></div><br> </div></div><br>_______________________________________________<br> Geysers mailing list<br> <a href="mailto:Geysers@lists.wallawalla.edu">Geysers@lists.wallawalla.edu</a><br> <a href="https://lists.wallawalla.edu/mailman/listinfo/geysers" target="_blank">https://lists.wallawalla.edu/mailman/listinfo/geysers</a><br></blockquote></div><br>
