[Geysers] More About White Dome--2005-2009

[Lynn Stephens]

I'm still catching up from my last trip and will be leaving again tomorrow for a few days, but did manage to skim The Sput last night and noted that Steve Gryc reported seeing no intervals of White Dome in the 40, 50, 60 or 70 minute runage during his 12-hour sit on White Dome.  From 2005 through 2009, reported intervals in these ranges were ABOUT 18-20% of the total intervals, with ABOUT half of these in the 41-50 minute category.  As Steve said, "long" intervals are probably underrepresented since many people are not likely to observe/report "long" intervals.
 
(Here's some data from 2005 through 2009 from my 2009 Report.  I have modified the original table to show 10 minute categories and to include the total number of observations.  Total does not equal 100% in all years due to rounding.)
