The main vent of Tantalus was bubbling. The entire pool had a greenish brown color but was clear enough for the main vent to be visible. The adjacent pool to the north was bubbling vigorously and more cloudy and yellow color. Root Pool was the same greenish brown color as Tantalus and high enough for the 2 pools to be connected by several inches of water. |

ROOT POOL water level has been fluctuating up and down about 1' in the past few days. One day it's up a foot, the next day it is down a foot. Both pools remain connected via the channel with these fluctuations. It's color is a brilliant seafoam green and the North pool has a small blooping boil. TANTALUS POOL is lower and down 1' below the wet high water mark. It is blue green in color and basically calm. only a few VERY small bubbles are breaking the surface. No activity from the edge features that were active this spring. |

Root pool is down 3' from high water mark. barely any water in the connecting channel. no boil. lime green in color. Tantalus is also very low and just a dribble of overflow into Tantalus Creek. Few bubbles that break the surface in its pool. Features along the island to the north are minimally active. EVERYTHING IS VERY LOW! Dishwater spring is active with a small boil, in light overflow. Muddy pools to the easy at the base of Dishwater have dropped ~8". The pool closest to the trees at DW's base have 2 boiling points. |

Root pool is an opalescent milky blue/ green color with blooping boil in the north pool. Pool level is the same, both pools connected with water in the channel. Tantalus pool is low, slight flow into the creek. Features along the north side by the tree island are not very active and the one sulfur yellow pool is now a light, muddy brown color. Dishwater spring has a very active boil, in overflow and there is a small 8" diameter breakout in the pool at the base of Dishwater spring, toward Tantalus. Breakout has a pretty moderate 2" roiling boil and is filling the pools at its base. |

Root pool is ~8" higher, lime green in color with a rolling boil in the north pool. Dishwater spring is high with a vigorous boil and overflowing into 1 pool at its base.

Root pool is down ~3' from my last observation. both pools have a minimal boil in them. color is murky green. The new Thing on the north edge of Tantalus pool close to the tree line of the island that divides Steamboats runoff (the delta) is still very active. it seems to cycle a bit from very active, burst ~3', to smaller 1' burst and then cycles back to bigger play. I have not seen it stop completely. Tantalus main pool is low and has a few boiling points with the center vent having a constant minimal roiling boil. |

Root pool water level is at the channel and is on the rise. Tantalus pool is high and very steamy. Low level bubblers, 1 - 2", in the same areas of the pool as previous days. ** @ 1300 Root pool structure changed at some point between this mornings observation and 1300. A large clump of soil and debris sluffed off the north pool channel, clogging the channel and changing how the 2 pools exchange water. @1300 Tantalus is one large pool with 1 large boil in the center. water level is high. color is similar to dark chocolate. |

arrived this afternoon to find Root pool down to below the channel but appears to be filling. Found Tantalus about 1.5 - 2' below the rim of the pool. Did something big! No obvious sign of an eruption: no splatter spray marks or debris. It is filling from Tantalus creek with multiple boiling areas in the main pool and one in the south runoff channel.

Another small boil toward the east. pool is high and thick chocolaty brown in appearance.

Tantalus is no longer acting as a mudpot like it was yesterday. The pool is quiet. I observed a small hole immediately east of tantalus after yesterday's 1726 SB push that was bubbling clear water to a couple inches. That hole has since enlarged and is now sitting inside a small crater with a raised edge. It is now perpetually blooping mud or muddy water to a few inches, accompanied by a steam locomotive chugging noise. |

water level in the pool is MUCH lower and has morphed into a black/gray sputtering mud pot splashing 1' in height from 2 vents. water in Tantalus Creek at the bridge is clear again. |

Tantalus spring is calm and no longer erupting. root pool is refilling and the "land bridge" connecting the 2 sides of the pool now has a water channel connecting the 2. The icky H2S smell that permeated this area for the past 3 days has greatly diminished! **1230 > Tantalus has one small boil (2 - 3") on the edge closest to the walkway and the water color is not so muddy brown as the last 2 days. On the Northern edge of the pool there are 2 areas that have sizzling blippy mud features in addition to a sulfurous yellow sizzler about 5' N of the pool and in a runoff channel that was first observed yesterday by TC. |

As seen from boardwalk nearest Tantalus Geyser, it was spouting/splashing dark, muddy water ftom two spots in muddy spring continuously. Lovely aroma wafted my way while I sat nearby watching Steamboat minor play. CB told me she saw it doing muddy splashes on 6-27-19 too. Tantalus Creek water muddy at bridge near Vixen. Collected gray mud at edges and high spots in creek. |

Noticed Tantalus Creek was a murky, muddy brown color at the bridge. He walked up toward Echinus to find out the origin of the color change and found Tantalus a muddy brown roiling pool with 3 areas that were erupting. 1 area to height of 3'. |

7/10/1995 = {generic morning rove start time} - Tantalus was muddy & steaming- my curiosity was up… Echinus? Yellow Funnel full & boiling. Marker still on Vixen since 5th? Pearl gurgling & steaming – I have seen no water for many days. Bastille was quiet- pool partially full. Couldn’t see the mud of Blue Mud - Sizzle Pot empty.- {NBK8} boiling 6-12”. And then I heard a new noise! Tantalus Geyser was erupting from 4 vents 5-10 ft high- water very muddy. Root Pool was all drained except for a pool about 4” deep- very impressive. - - -
3:30 pm: Activity @ Tantalus geyser down – boils over four vents Root Pool has boils over the vents of the two pools w/a water channel connecting them. Water level down a few inches @ Yellow Funnel & boils over vent. Emerald has bubble release too. |
