[Geysers] Bulger's Hole

[Ben Hoppe]

Just got back from a short trip to the Park, and I managed to see a few
eruptions of Bulger's Hole. For those of you who have seen it when the small
sinter bridge was still there, it is now gone (not sure how long it has been
gone). The eruptions I saw were all with lower light, so it was difficult to
tell whether or not the water was milky or not. It was quite clear from what
I could see.

All eruptions either began during a major of Bulger Geyser (full height,
duration > 5min) or immediately after an "intermediate eruption" of Bulger
(full height, duration ~ 30sec). You'd see the water come up in Bulger's
Hole, and the bursting eruption would then commence. The eruption has a very
interesting chugging sound. It sounds extraordinarily violent in my opinion.
Many rocks are thrown quite often, however, I think some of these rocks are
actually washed in from the back edge of the crater during the eruption and
spit right back out.

Here is a link to a "series" of two eruptions of Bulger.

eruption with a pause... I don't really know how to classify it. The
eruption was interrupted by another eruption of Bulger. This was a series
that started after an intermediate eruption of Bulger, and between the two
eruptions of Bulger's Hole, Bulger had another intermediate eruption. I
apologize for the shakiness at the start. I was trying to pull out a radio
to call it while recording (easier said than done).

Also, attached is a picture from an eruption on Thursday (7/28/11). The
major eruption of Bulger is shown in the background for comparison.
