<DIV>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."</DIV>
<DIV> </DIV>
<DIV>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.</DIV>

<P style="MARGIN: 0px" data-mce-style="margin: 0px;"> 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?</P>
