8/1/1992 - no time noted - the new thermal features continues to drop in water level – It seem quite a bit smaller with no run-off and it is erupting only about 1 foot high. Son of Green Dragon- water level has dropped about 2 feet and the now very murky water is boiling violently with intermittent burst like activity |

7/29/1992 - no time noted ~ afternoon - maintenance crew removed barricades to open the Back Basin in late afternoon. Rick Hutchinson feels that we are not in imminent danger of hydrothermal explosion and we’ll get the boardwalk crew in to move the walk over a ways. There is a strong barricade at the new spouter. Please continue to monitor the area carefully- report here anything new or unusual . |

7/28/1992 - no time noted - The new thermal feature seems to be slowing down some- The western edges of the pool (away from the boardwalk) is no longer boiling There were about 8-10 very smalls [sic] vents. That have stopped. There is also very little to no runoff!! |

7/27 - no time noted - New Thermal Area – The spouter is still spouting -But there is little or no runoff. {Bastille} Corral [sic] Springs is way down about 12 inches. The depressions are getting bigger. Fearless is way down also. But that is not unusual The rest of the back basin is still very muddy & boiling-Porcelain is the same. |

7/19/1992 - inferred time after palpitator entry - Things still cooking!! in the Back Basin. The new spouter is still very active – although the ground in the area has become significantly hotter. You can feel the heat coming through the boardwalk. There are several new holes around. And the cavity across from the new spouter keeps getting bigger everyday. |

7/18/1992 - approx time based on other entries - The whole area around the new spouter {bastille} was steaming pretty actively this morning. The trees in the surrounding area a [sic] cooking. Several trees have fallen overnight – It looks like a new hole may have formed on the other side of the Boardwalk. Right next to Double Bulger.
The new spouter is beginning to undercut the boardwalk. It is spitting more H20 onto the Boardwalk. |

7/17/92 again - no time noted - We decided that any alternative routes would invite off trail exploration into equally dangerous areas so did not flag a route. Especially southeast of Vixen is a depression with holes all along the margin. {nbk6} The depression from memory, might be 5’ x 7’ or bigger. It looks trecherous [sic]. So we decided to stick with the boardwalk.
Duncan Foley was here…. He has a soil thermometer which registers to 300ºF so we went to the hot area.
With soil temps of 199.2ºF, he says we have hot water very close to the surface. Makes sense. New boardwalk in order to circumvent the hazardous area seems essential. A visitor made the suggestion of using heat-sensing apparatus in order to chose a new safe route. Duncan Foley said he would come back tomorrow in the AM to re-check temps. |

7/17/92 - no time noted - The new spouter looks a little bigger – There is a lot more H20 in it then when I last saw it on Tuesday evening. Also the pools in Back Basin seem to be boiling more violently. Mystic is very muddy. |

7/17/1992 - no time noted - The most dramatic change is in the area near the Porkchop spur & the new spouter. The ground is very hot over a large area. Temps to follow. There appears to be a steaming crack, parallel to the Pork chop spur trail on the east side.
Much water runoff from the new spouter, making silt-like channels. Hole is at least 4 feet across. Spouting up onto board walk. [Bastille] |

The violently Boiling spring near Porkchop is not Corral [sic] Spring – it is a New Geyser!! ← Spouter. I discovered it this morning at 8:15 about 2 inches in diameter- this afternoon at 1450 it had increased to about 3-4 ft in diameter & was erupting continuously 3-6 ft |
