Geysers of Yellowstone   



  Bulger's Hole
Feature Type: Geyser
Geyser/Spring Type: Fountain geyser

Upper Geyser Basin
Grand and Castle Group

Bulger's Hole is one of the newer erupting features of the Upper Basin, having appeared some time during 2011. It is a conspicuous hole/crater between Bulger Geyser (Bulger Spring) and the boardwalk near Sawmill Geyser. When active it would play to a height of a few feet, with a duration of 3 or 4 minutes. Intervals as short as 1 hour, 6 minutes are recorded at geysertimes.org, but most intervals seem to be of the order of a day or more. Some but not all eruptions were simultaneous with eruptions from Bulger Geyser.

What to look for:
No eruptions of this geyser have been reported since 2012. According to recent reports, the vent has filled with sand and debris. If so, the thing to "look for" is simply a clearing of the vent, indicating the possibility that a recent eruption, or at least filling of the vent, has occurred. Until then, there's not much to look for.
