[Geysers] Geyser Report: Young Hopeful/Gray Bulger

[TSBryan at aol.com]

While I was in the park, late May to early June, I watched these vents  
several times. The action seemed all-but-identical each time. As described by  
Gryc, but the cycles (such as from the jetting vent, around through  the 
bursting vents, and back to the jetting vent) took no longer than 5  minutes, 
if that.The maximum height was around 4 feet, maybe as high as 6  feet in 
spurts. See attached photo. At no time did I observe what could be  called 
"continuous bursting."
 
As for the naming here, I pretty much agree with Gryc. I'm pretty sure  
these active vents -- the jet and the bursters -- all belong to Gray  Bulger, I 
think the Young Hopeful Geyser of old either no longer exists or has  bee 
severely modified by time. Clearly, the geyser farthest from the road and  
right at the lakeside is Artesia.

I was  in the park all last week.  Following up on July posts concerning 
Young  Hopeful geyser from Stephen Eide and Dan Schaffer, I spent some time at 
 Firehole Lake.  Dan had seen what I will call “major eruptions" of Young  
Hopeful (or Gray Bulger) to a height of 6 to 8 feet.  Stephen had  witnessed 
later ones of up to 10 feet.  The jetting eruptions I witnessed  were 
between 10 and 15 feet. The intervals I timed were all longer than  Eide’s, 
ranging from 12 minutes 42 seconds to 41 minutes 54 seconds.  I  saw twelve 
eruptions on Tuesday, September 8.  I went back on Thursday,  September 10 to 
take more data and saw two eruptions for a closed interval of  14 minutes 15 
seconds.  I waited another 2 hours and 35 minutes and saw  nothing but the 
usual continuous bursting from four vents and sporadic small  bursts from two 
others.  Thinking that the geyser might be erupting in  series, I returned 
the next morning.  I waited over an hour and a half  and saw no major 
eruption.  Now I’m wondering if Young Hopeful (or Gray  Bulger) has stopped the 
major eruptions altogether.  Has anyone seen this  geyser jetting at all since 
16:25, September 10?
