The NPS has extracted part of the data from Table 7 of the USGS Professional Paper on Norris and updated the list through the last major eruption (May 2005). The list is available at http://www.nps.gov/yell/planyourvisit/upload/yell255.pdf. In February 2007 it was reported that Steamboat had had a major eruption because witnesses saw a huge steam cloud and Cistern Spring was draining. Based on observations and analysis of temperature data from Steamboat's runoff channels, Hank Heasler and Cheryl Jaworowski concluded Steamboat had not had a major eruption. Their paper "Analysis of a Suggested Major Eruption of Steamboat Geyser on 21 February 2007" is available on-line at http://www.gosa.org/news/steamboat_21_february_2007.pdf Lynn Stephens > Date: Fri, 4 Dec 2009 20:06:33 -0500 > From: jgra at loc.gov > To: geysers at lists.wallawalla.edu > Subject: RE: [Geysers] Geyser question > > Lynn, > Maybe I missed it, but can you also tell us what Steamboat did in > 1966? > A google showed 24 eruptions in 1964 and then only one in 1969, but was > labelled "incomplete". > I don't have any reliable data of my own. > TIA > Jim Graber > > >>> Lynn Stephens <lstephens2006 at hotmail.com> 12/3/2009 11:19:03 PM > >>> > > I agree a photo would help, and possible a bit more precision than > "mid-June." > > > > Based on Marler's monthly reports, it wasn't Link, Splendid (not > active), Morning (two eruptions in August), or Fan and Mortar (no > mention in Marler's monthly reports). > > > > In his September 1966 report, Marler said Sapphire was active, but the > eruptions were small-- > > "Sapphire continues to erupt on about 15 minute intervals.
