[Geysers] Geyser Report May 28

[Lynn Stephens]

THIS REPORT IS FOR THE PERSONAL USE OF THE READERS OF THE LISTSERV AND IS NOT TO BE REPRODUCED BY ANY METHOD FOR ANY OTHER PURPOSE, INCLUDING PUBLICATION IN THE SPUT OR OTHER PLACES UNLESS YOU HAVE CONTACTED ME FOR MY PERMISSION TO DO SO.
 
I realized I haven't been putting my disclaimer on the reports I've been filing.  If you're a fairly recent subscriber to the listserv, you may not be familiar with the fact that posts on the listserv may be reproduced in The Sput for publication unless the author of the post states otherwise.  I plan to write a Sput article based on my observations during my trip, and don't want to see my analysis reproduced in other places either, which is why I attach the disclaimer.  Please apply this disclaimer to previous posts I have made this season.
 
I was going to get back to town at a "reasonable" hour to compile statistics on some geysers and write a report for today.  Unfortunately, Gemini threw a wrench into my plans.
 
The day started "as usual" with Gemini.  Steve Robinson and I watched a series of 7 eruptions that started at 0724.  Pebble had been overflowing prior to the start of the series.  The next series, which conisted of 5 eruptions, started at 1153.  Pebble was not overflowing prior to the start of the series.  The third series of the day, which also consisted of 5 eruptions, started at 1531, and Pebble was also not overflowing prior to the start of the series.  
 
I left the area following the end of the third series of the day and returned at 1845.  Pebble's water level was above the "west crack" vent, but below the bottom of the orange rock we have been using to measure water levels in Pebble.  This water level indicated to me that Gemini had not erupted while I was out of the area.  Pebble's water level continued to slowly rise over the next 60 minutes until it reached overflow.  The overflow was out of sight down the bank of the hill leading into Cave by 1955.  Over the next 2 1/2 hours I watched Pebble overflow. Gemini periodically filled with water, bubbled a little, then drained.  Earlier in the week I had been recording each of these rises.  This evening I wasn't.  At 2238, 7 hours 3 minutes after the start of the preceding series I gave up.  Prior to that the longest interval between series I had recorded had been 4h55m.  I hated to give up because (1) I wanted to see just how long the interval was going to be, and (2) I hoped Crack might erupt.  But somewhere in the back of my mind I remembered a season when Gemini was active but sometimes there were days between the series.
 
On another note, I recorded three intervals of A-0 today:  24, 24, and 25 minutes.  Durations were all about 30-40 seconds.
 
I drove away from an eruption of Labial this morning at 1105.  I knew it was getting close and had moved the pickup from Pink Cone up across from Bead/Box Spring/Labial.  I decided to sacrifice Labial to return to Gemini.  Scott Bryan said I hadn't gotten as far as the little bridge when Labial erupted.  I did see the next eruption of Labial at 1706, for an interval of 6 hours 1 minute.
