The Keller and Schrayer accounts were of the same eruption that Paul Strasser describes below, which took place on July 29, 2006.  There was also a write-up in the Sput (v. 20 no. 4, Oct 2006) with more extensive descriptions by Kendall Madsen and Mike Keller, as well as information obtained by Hank Heasler when he examined the area at that time.  There were repeated attempts to put an electronic monitor on Black Diamond, but it kept tossing the device out of the pool. Based on visual reports and physical evidence, Black Diamond has been having explosive eruptions of this nature at infrequent and highly erratic intervals since July 13, 2006. --Tara Cross fanandmortar@hotmail.com <hr id="stopSpelling">From: upperbasin@comcast.net To: geysers@lists.wallawalla.edu Subject: RE: [Geysers] Photograph of Black Diamond eruption (Stephens) Date: Tue, 26 May 2009 08:22:38 -0600 <style> .ExternalClass .EC_shape {;} </style> <style> </style> <style> .ExternalClass p.EC_MsoNormal, .ExternalClass li.EC_MsoNormal, .ExternalClass div.EC_MsoNormal {margin-bottom:.0001pt;font-size:12.0pt;font-family:'Times New Roman';} .ExternalClass h1 {margin-right:0in;margin-bottom:8.0pt;margin-left:0in;page-break-before:always;page-break-after:avoid;font-size:18.0pt;font-family:Arial;color:#003366;text-transform:uppercase;font-weight:normal;} .ExternalClass h2 {margin-right:0in;margin-bottom:3.0pt;margin-left:0in;text-indent:0in;page-break-after:avoid;font-size:14.0pt;font-family:Arial;color:#003366;font-weight:normal;} .ExternalClass h3 {margin-right:0in;margin-bottom:6.0pt;margin-left:0in;text-indent:0in;page-break-after:avoid;font-size:12.0pt;font-family:Arial;color:#003366;font-weight:normal;} .ExternalClass p.EC_MsoBodyText, .ExternalClass li.EC_MsoBodyText, .ExternalClass div.EC_MsoBodyText {margin-right:0in;margin-bottom:4.0pt;margin-left:0in;text-align:justify;font-size:10.0pt;font-family:Arial;color:black;} .ExternalClass a:link, .ExternalClass span.EC_MsoHyperlink {color:blue;text-decoration:underline;} .ExternalClass a:visited, .ExternalClass span.EC_MsoHyperlinkFollowed {color:blue;text-decoration:underline;} .ExternalClass span.EC_EmailStyle18 {font-family:Arial;color:navy;} @page Section1 {size:8.5in 11.0in;} .ExternalClass div.EC_Section1 {page:Section1;} .ExternalClass ol {margin-bottom:0in;} .ExternalClass ul {margin-bottom:0in;} </style> <div class="EC_Section1"> We need to be clear.  This was an eruption from the pool containing Black Diamond Geyser.  I saw an eruption of it in 2007 that was a bit smaller than this eruption.  Other gazers had seen larger eruptions (and photographed it from across the highway), and the evidence of even larger eruptions was present on the boardwalk and nearby trees – splashes of muddy water leaving bits of elongated mud a considerable distance from the pool.   The eruption I saw (along with several other gazers, including Mike Keller) looked like the photo.  It was amazingly black and filled with debris and glop, albeit shorter.   As Scott noted, the article was filled with inaccuracies (no geysers at Biscuit Basin?  And even if they meant “no geysers in this area of Biscuit Basin” it’s still wrong), but the most inaccurate part of it is the primary point:  that this was a rare hydrothermal explosion.    No, it was an eruption of an infrequent geyser.  Now, was this particular eruption so large that it shattered the vent structure?  We have no idea, because the pool is so muddy and dark.  I suppose Black Diamond could have done a Porkchop on us, but the only way we will know is to see if there are additional eruptions in the next month/year.   I have no problem with Scott writing a little comment to the editors about this.   Paul Strasser   <div> <div class="EC_MsoNormal" style="text-align: center;" align="center"> <hr align="center" size="2" width="100%"> </div> From: geysers-bounces@lists.wallawalla.edu [mailto:geysers-bounces@lists.wallawalla.edu] On Behalf Of Jack Ashe Sent: Monday, May 25, 2009 8:14 AM To: Geyser Observation Reports Subject: Re: [Geysers] Photograph of Black Diamond eruption (Stephens) </div>   <div> <div> Hydrothermal or not, that is the quesiton! </div> <div>   </div> <div> Isn't the assertion in the article that this was not a geyser eruption but rather a hydrothermal explosion resulting in geologic effect similar to the Pocket Basin explosion crater, Indian Pond or the Duck Lake events? </div> <div> Was this NOT a true hydrothermal explosion but just a "messy" geyser eruption?  </div> <div>   </div> <div>  If it is a hydrothermal explosion, I have been informed that these probably result  from a sudden drop in water pressure over the thermal source. Did that occur at Black Diamond?? </div> <div>   </div> <div> Jack   </div> <div>   <div> <div class="EC_MsoNormal" style="text-align: center;" align="center"> <hr align="center" size="1" width="100%"> </div> From: "TSBryan@aol.com" <TSBryan@aol.com> To: geysers@lists.wallawalla.edu Sent: Sunday, May 24, 2009 4:35:27 PM Subject: Re: [Geysers] Photograph of Black Diamond eruption (Stephens) <div> <div> Need I point out the errors in this article.
