7-5-2018 CORPORAL BBEV 1201 See Note under Steamboat
Porcelain Basin still very active, but appears drier. Congress pool down 4-6" from yesterday, still boiling vigorously. Emerald Springs and Monarch runoff appears to have increased. Monarch geyser crater has clearer water and much fuller. Corperal boiling, runoff wet. Cistern did not look any different, boiling steadily, just at overflow. Emerald Springs is still cloudy but with noticeably less boiling.

Two eruptions in this time frame - Starts are different – more convection and upwelling before it starts as it used to, or if that is the start it is very very different, so I don’t have good start times yet until I figure it out! Water level is low, but it does reach overflow during the eruption, about 10 feet out. Superb growling and grumbling from Dog Leg! |

Corporal and Dog Leg water levels are back to predisturbance levels, after going way way up, then followed by very very low for weeks. I did not get a full cycle to check intervals and durations because Vixen was vexing. |

07/10/1976 Corporal Geyser - - feature appears to be more active than normal. The wash from the feature extended beyond normal runoff channel and was evident on the trail between Veteran and the “T” in the trail by bridge at Tantalus. |

Corporal: the usual overflow activity (periodic with draining level of pool down ~ 6”) which has not been apparent in the last two weeks, was noticed happening today. Timed sequence: 22 min interval between one drain period and another – 15 ½ min after it started to drain, it started to fill, overflow lasted ~ 1 min, draining : ~1 min, filling about 5 min. |

05/12/1973 Each eruption of Veteran was followed by bubbling and runoff of Corporal. Dog’s Leg water level dropped a ft. as Corporal filled & overflowed – then filled up as overflow of Corporal ceased. |

For several days I’ve noticed that Corporal Geyser was having greater than usual run-off at times, however every time I went by Corporal it would be 3”-4” below the edge. Today I witnessed the “eruption”. The pool started to fill and bubble until it rose to overflowing. The bubbling action was relatively gentle. Approx 20 gal of water ran down the run-off channel, the bubbling stopped, and the level dropped. A dull thumping was apparent during the bubbling activity. {no specific time} |

Corporal Geyser – the heat has shifted to here – apparently from “The Dog’s Leg.” There is bubbling in pool of Corporal, the water in it is turbid, & there is now no runoff from The Dog’s Leg. In addition, The Dog’s Leg has lost most of its Sulphur deposit. |
