Seep discharge (est 1/8 gpm) All of the basin & vents are lined with 30-40cm long filimentous algae covered bacteria ranging from creamy white in the warmest portions to orange-brown-red like the color of an Irish setter dog. |

11/15/1981 Rubble The sneaky little devil waited until after Fred & I cleared out (in late Sept) its planned runoff channel & filled in the trench it has dug in the trail before it started erupting again. It has dug a wonderful 6” deep trench (that looks perfect for twisting ankles) down the middle of the trail toward Palpitator. The H20 is clear & 148º. It is currently active & erupting. |

8-10-81 Rubble must be erupting 2-3 times per day since the runoff channel is always wet & my markers are never there when I return. The path was wet almost all the way to Palpitator today so it must put out alot of water. |

Rubble Geyser – great deal of overflow from Rubble. The feature’s overflow has flooded the walk below the feature. Evidently this vigorous activity occurred last night or early this morning – { flooded because washout out channel near drain tile, channel now repaired} |

Watched Rubble “erupt” ~ Area fills to overflowing. Heavy overflow before eruption. About the time overflow reaches the walk, the vent starts bubbling vigorously 6”-24”. Overflow becomes less. Activity stops after a minute or two and what what that remains drains down vent. |

A new thermal feature located about 48 feet north west of the west edge of Corporal Geyser’s pool apparently has increased in activity with much erosion during the night and its first known recent play occurring between 9:40 & 10:10 AM. This is probably an enlargement or extension of the “small {new} vent” which was reported to have started to play in July in the Norris Thermal record.
The thermal feature is aligned on a NW-SE direction with Corporal & Dog’s Leg, apparently along a joint, with its greatest dimension in this direction. It is irregular in shape with its present measurements as follows: Length: 11’8” (starting under a “live” small green lodgepole pine on the N.W. to about 1 ½ feet beyond an old dead stump on the SE); width: varying from 34 to 72 inches, and maximum depth: 11 inches.
Play was observed at 4:35, 5:24, 6:09, 6:58 (average interval ~~ 48 minutes). The play was preceded by increases in the amount of steam coming out of the ground, then a rapid filling and overflowing – starting first at the SE end, then spreading NW from other low points {filling phase lasting 40-60 seconds}. This was immediately followed by a vigorous boiling action throwing water, sand & geyserite chips to a height of 1 foot. “The eruption”, again starting & ending first at the SE end and starting & ending last at the NW end {duration: 2 minutes}. During the last 30-40 seconds of the play there is rapid draining of the water back into the ground finished off near the NW end by a final bubbling sound down below the surface. It is quite a sensation to set at the edge of the feature and feel the ground below you shaking vigorously! The bottom of the feature is made of small loose geyserite thin plates and porous tabular bodies of small geyserite fragments. R.A.H. |
