07/14/1976 Pequito geyser again has been the target for vandals, rocks, some bigger than fist size have been thrown in area, probably to see if geyser will move them out of the way. Also it still appears to be spouting continuously. |

07/14/1976 Pequito was in a forceful water phase at 0830. The eroded channels near the boardwalk were full of water & bubbling quite nicely. Pinwheel was quiet- no bubbles seen at all. |

06/30/1976 New Geyser (called “Fife & Drums” by some, “Frijole” by others) was in a minor water phase at 0845. Eroded channels near boardwalk were dry, but Pinwheel was splashing away and emitting loud popping sounds. |

06/29/1976 {no times noted} Watched new geyser & Pinwheel for 25 min. At beginning of watch, new geyser was erupting about 1’ high & its eroded channel by the boardwalk was dry. Then it began pulsing higher & the channel filled with water. Pinwheel began emitting large bubbles from its vent & splashing as high as 2’ was seen. Big Whirligig began erupting after 5 minutes of this type of play. |

06/20/1976 The new geyser near Pinwheel has opened up a couple of more vents close to the boardwalk. Will have to a watch [sic] on them. The new feature, Pinwheel, and Splutter Pot all seem to be connected. |

06/02/1976 One of the little bubblers near the boardwalk near the platform in Porc. Has become a spouter shooting steam and water 6’-10’. Could be a problem if wind blowing wrong. |
