6/5 At 5:13p yesterday (6/4) I approached Minute. There was no water coming out the vent although you could hear water bubbling and see an occasional wisp of steam. The thick white sinter was very apparent around the vent and the grey geyserite spine rocks were dry. The “new pool” was less full and there was no overflow. It appeared that Minute had acted like a geyser instead of a perpetual spouter. After seeing Echinus at 615pm for 4min I returned to check on Minute. From a distance I could see a huge column of steam appearing to be an eruption. At 1830 Minute was erupting to about 4’ with the “new pool” overflowing. This continued until ?? since I left at 1849. This a.m. (6/5) at 820 am Minute was behavior like a weak spouter with the water barely breaking the surface and rising slowly to 2”-4”. Stand by The “Minute”
Minute cont… At about 2p Minute was dry when Dave walked by. Around 4p erupting as a geyser. The pool was very full & overflowing. |

New Feature between Monarch Geyser and Minute Geyser. The feature is east of the trail and as you face the runoff channel from Emerald Spring - - this new pool is to the right. Distance from trail is appropriately 30 feet. Water color is cloudy grey and it is hot. |

09/27/1975 BRANCH SPRING {generic time}
Overflow was also occurring periodically in circular spring next to Minute Geyser. The several intervals observed were ~ 2 min duration of filling (~20 sec), overflowing and draining (down about 3”). There was ~45 sec of quiescence between these periods of activity. However, there was some fluctuation of the durations of each section of activity. |
