The southeastern vent of Impatient Miser Geyser's basin (= Pool Geyser's vent 4 of Landis, 1989) is occasionally erupting (small/low), as seen previously on 6/3/2019, 6/7/2019, and 6/11/2019. |

What appears to be the southeastern vent is still active - same behavior as on 6/3/2019 & 6/7/2019. This is Pool Geyser's vent 4 of Landis (1989) - Hydrothermal Observations in Yellowstone National Park, 1988, pp. 184, 341. This is vent 7 of Wolf & Paperiello, 1989, Report on the Kaleidoscope & Sprinkler Groups, pp. 25, 26, 32, 33. Frequently active today - usually very low to low spouting from a non-water filled basin. |

What appears to be the southeastern vent is active again - same behavior as 4 days ago (= Pool Geyser's vent 4 of Landis, 1989 - Hydrothermal Observations in Yellowstone National Park, 1988, pp. 184, 341) (= vent 7 of Wolf & Paperiello, 1989, Report on the Kaleidoscope & Sprinkler Groups, pp. 25, 26, 32, 33). |

No eruptions today from the southwestern vent or the northeastern vent - these are the normal two vents for Impatient Miser Geyser eruptions (four vents are in the basin). No standing water in the basin today. However, frequent, very low to low eruptions (with brief pauses) were coming from the southeastern vent (= Pool Geyser's vent 4 of Landis, 1989 - Hydrothermal Observations in Yellowstone National Park, 1988, pp. 184, 341), which I've never seen active before. Vent 4 had same activity today both during & between adjacent Little Miser Geyser's eruptions (which affected Impatient Miser's vents 1 & 3 eruptions in previous years - the normal vents). |

Impatient Miser Geyser's basin was water-filled - all vents in the basin were covered. Water-filled basin formed 1 body of water with the immediately-adjacent hot spring pool to the north ("Sprinkler Pool"). |
