Water level 4 to 6 inches below overflow. Pool is pulsating and streams of bubbles rising. Some bubbles are flashing and the water occasionally rises about an inch. Slight sizzling sound after flashing stops and water drops. |

Watched Topsoil Spring for about an hour. Low water level (~1 foot below border). The central vent is submerged, as is the proximal-most basin. Activity varies frequently from a ~still pool with moderately light bubbling to relatively rapid pool pulsing events, with more vigorous bubbling. Northeastern side vent & the two southwestern side vents often had bubbling, sometimes audibly. |

About 8 inches below overflow, clear water. Sloshing and thumping almost continually with occasional brief pauses of <10 sec where pool calms and the tiny vent on the far side stops spitting. Pauses observed to occur anywhere from 40 sec to ~7 min apart. Sporadic boils to a few inches and during that one long duration saw a few small splashes <8 inches. |

Topsoil spring is rocking with strong convection in the pool. It is about 6-8 inches below overflow. I did see one splash to about a foot at 1436. Sometimes you can hear and feel the ground thump. I saw a second splash at 1446. It has pauses in the activity about every three minutes |

Was about 2 inches below overflow and dropping (?) about 30 minutes before Grand tonight. Several audible thumps were heard. No bubbles or ripples on surface, and thumps sounded deep underground down in the plumbing system, instead of close to the surface like previously |
