low quiet pool @0841 - 1st bubble @0843 w slight outwash- heavy boil commenced @1:31 after 1st bubble with immediate heavy outflow - dropped out of ovfl @3:55 - next 1st bubble @0849 - it got quiet this time for a few seconds before launching into the heavy boil @0855 - so generally a 6min cycle with D ~4min if timing start from 1st bubble - if timing heavy boil to end D=approx 2.5 min |

1849 on arrival, constant rolling "boil" with rippling all the way to edge of pool. Hearing a hissing or sizzly noise from nearby, I think to right of pool. 1853, water dropped below runoff channel. 1854 rising into runoff. Pool stopped bubbling and started a full sizzle. 1855 huge roil up that led to constant wave action to edges and into overflow. Looks like a bowl of soft Jello being shaken. 1857 back to center bubble and dropped out of overflow. 1900 refill starting. 1901 bubbling stopped and jiggle started. 1902 full on bubbling jiggle and into overflow. This thing is cool to watch! Oh, color is blue with yellow pool so green. 1904 back below overflow. At no time did it drain - drop below overflow means out of the runoff channel. That's as far as it dropped. Headed back to Cistern! |

Water is opaque, dirty beige. Small bubbling in middle causing ripples to edge. Just below overflow to "V" that leads to runoff channel. Feature to left with 2 holes is gurgling and burping but no water seen.
1226 Large roiling a foot or so in diameter began, splashing to a foot, pool filled fully and overflowed. Returned to quiet by 1228.
1230 filling. 1231 roiling and splashing to overflow. Dropped.
1236 fill and roil and splash. Overflow. Calm and drop by 1238.
1240 filling, 1241 start, overflow, 1242 calm and drop, 1243 water down from V.
1245 filling, 1246 start, calming 1247. Droppong. Out of V at 1249.
When I say drop, its just to top of pool edge down from V for overflow. Does not drain.
Thunder heard, dark clouds rolling in. Up the hill I go! |

Dr Nordstrom - USGS doing research at Minute and pool next to it (Branch Spring?) - monitored pH & temperature
Minute – Boiling 7.19 pH
Branch – 80° 3.19 pH
He says it may be because the cooler more acidic is drawing water from closer to the surface and hotter more neutral from lower down [generic day time] |
