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

Basin
Upper Geyser Basin
Complex
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.
