Sorry -- got sidetracked with other stuff. My mystery 17 shows Little Bulger Geyser, at Shoshone, in July 1976 before the parasitic vent became dominant. Jeff Cross asked about the history of that vent. Well, I certainly don't know, but I feel it probably was "always" there, just not active. Now here is Bryan mystery 18, July 1985.
