[Geysers] Geyser report May 16

[TSBryan at aol.com]

A rather chilly, uniformly cloudy day, but dry until just after noon. But  
then since Grand (1 burst), Beehive (9 minute Indicator, accompanied during the  
eruption by the C-C Indicator to about 2 feet), Lion initial, Oblong and 
Plume  all decided to erupt between 1130 and 1200, I left. And drove all the way 
to  West in pouring rain.
 
Not much to report, therefore. Fan and Mortar had not gone as of noon -- up  
to 9 1/2 days.
 
Grand's four intervals since yesterday morning were 6h32m, 7h08m, 6h51m,  and 
8h05m.
 
Grotto was in marathon -- again.
 
Castle had a minor last evening, giving intervals of 12h49m followed by the  
minor of 4h02m.
 
 
I again replaced the marker at Silex, which was very murky at 0750. I  
presume these nighttime "events" are eruptions, and the activity of Celestine  
generally supports that. In that case, this is an interval of probably a little  
more than 24 hours. However, I do know that Silex can have very heavy but  
non-eruptive overflows. However, too, I haven't seen one of those reach my  marker. 
So...
 
At about 0750, Fountain had evidently ended its eruption a short time  
before. But it was so low that water could not be seen from the overlook, and it  
was barely visible in Morning. Question: Has anybody ever seen Twig Geyser  
undergoing a _true_, forceful steam phase? I haven't, but there it was.
