There was a major eruption of Steamboat on June 19, per USGS Professional Paper 1456 "The Geology and Remarkable Thermal Activity of Norris Geyser Basin, Yellowstone National Park, Wyoming," by White, Hutchinson, and Keith. It can be accessed at http://pubs.usgs.gov/pp/1456/pp1456_text.pdf. Table 7 has a list of recorded major Steamboat eruptions 1878 through June 1984. There were "at least 10" major eruptions in 1966, with intervals from "11 to 77 days". The table says there was a "12-min. water phase June 19; 10-12 min water phase Aug. 10 (Norris Museum records)" 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.
