3rd day of temperature dropping to near-ambient at night. Onset ~2230, from ~37°C to - ~10°C in a ~quarter. At ~45°C around 0745, needing what seems to be more than an hour to get to there from near-ambient. Would almost think Porkchop has developed a diurnal nature, though this would need in-basin confirmation I'd imagine. |

Porkchop still overflowing to the south, but not as heavily as last week. The west side still pools by the boardwalk in the trees but doesn't continue northerly to the Second Erupter channel. The east side still drains down into the Gray Lakes channel of Tantalus. On my first visit in the morning I didn't see steam in that channel, but later in the day could see water. |

Full, overflowing to the south. Runoff goes two directions, one leg east towards the Gray Lakes branch of Tantalus, the other leg flows west to puddle near the boardwalk in the trees, then curves north to join Second Erupter's runoff channel near the boardwalk crossing. |

A note from Bob about reading the Porkchop graph: Need to read the logger considering ambient temperatures (daily high & low air temperatures) and precipitation. Not an exact science. Main thing is a low drop not weather related followed over the next 12 to 24 hours by a rise not weather related. Steamboat “pause” (drop) typically 2 days later followed by recovery to a peak 1 to 2 days later followed by a slow taper to next “pause”. |

This note is from my brother, Bob Partner, and gives additional information regarding DGInc's Echinus notes on 2/19 & 3/3. The temperature graph at Pork Chop somewhat mimics the Steamboat temps (& the Steamboat graph has been down except for now showing data Feb 28-Mar 3). -Polly. “Event” at Norris late on 2/17 – early 2/18. Anomaly in Constant Geyser (very low spike in temp rather than normal larger spike), and big drop in temp at Porkchop, followed shortly after by frequent minors at Echinus. Drop in temp and steady increase in flow from Tantalus Creek (need to go to the “stream flow data” page). Has some of the look of another disturbance, but…... Interesting that there is a temperature recovery on Tantalus early on the 18th while water flow continued to increase – got unusually high. Storm hit about that time, but precipitation totals (less than 0.1 inch per hour, so only light precipitation) would not account for the large increase in water volume or initial drop in temp, and air temps at the time did not fluctuate a lot, so temp drop would not relate to the storm either. Definitely some kind of “event” in the basin with all the changes occurring about the same time frame. |

It appears as if Porkchop's water level is recovering. Hit ±11°C (±52°F) on 14th of October, shortly after that a sharp increase to more than ±35°C (±95°F). Temperature still variable, sometimes increasing and sometimes dropping below ±30°C (±86°F). |

JarnoO |
Temperature made a remarkable drop from ±47°C (±117°F) to ±24°C (±75°F) between Sep. 4 and Oct. 4. This has likely nothing to do with the changing weather, as the start of the drop was a couple of days before the Nuphar Lake logger began logging lower temperatures. |

More observations on Dr. Morey’s Porkchop: it was practically empty but erupting at around 10:30, 1½ inches below the rim but shooting a fine pencil like ray of water 15-20 feet, here each burst of water was like what one would hear of the exhaust pipe of an old John Deere “A” tractor was sputtering a little over a foot below the water level – both in sounds and in the time interval between each sputter. At approximately 6:30 PM the pool was almost empty again, but with little bubbling action; it soon increased again however. The vent at the base of the pool from which DR Morey’s PorkChop plays is roughly an equalangular triangle, about 3” long on the base & 1¼ in for the height. |
