[Geysers] Geyser report June 1

[TSBryan at aol.com]

My cold has eased enough to allow me a few hours in the basins today, but I  
most definitely did not want to overdo. So much of the following is summaries  
taken from the logbook.
 
First to note that yesterday's Giant started with Mastiff. Mike Frazier was  
the only person there, and it was very cold and steamy. He heard Mastiff more  
than saw it, but finally did see some jetting that was quite high (like 40 or 
50  feet?). Then Giant started a minute or so later.
 
Grotto was off, between normal eruptions, another of which began during  
Giant.
 
Yesterday, too, Beehive erupted at 1308 with no Indicator. Today, Beehive  
had not gone as of 1230.
 
Grand this morning was on an interval of 6h 33m and was rather unexpected  
since it started on a 28-minute delay Turban: D0/G1Q.
 
Plume has lengthened its intervals by a little. Yesterday, intervals were  
recorded as 64, 68, 63 and 71 minutes; today saw 62, 68 and 56 minutes.
 
>From the logbook, Great Fountain (including one inferred double and one  
approximate interval) gives us 10 intervals so far this spring. They range from  
10h 34m to 18h 26m, with a mean of 12h 51m. (Eliminate that 18 hour job, then  
the longest is 13h 24m and the mean is 12h 13m.) The average of 6 overflows is 
 87.5 minutes (range 72 to 102); the average of 7 pauses is 3.14 minutes 
(range 0  to 8).
 
Only 5 closed intervals are available for Fountain -- or at least, they are  
probably closed intervals. The range is 4h 28m to 8h 46m, mean 6h 49m. I think 
 these are real because the duration has been recorded four times, and they 
are  all long: 33, 35 1/2, and 42 minutes!
 
That's all for today.
