Attempts to erupt but fails. Nice boil that looks like it will erupt, stays boiling for 4+m, then stops and pool falls below overflow. Constants pool is being filled by 5 small erupters that seem to run along a line to the north east (up toward the Graceful area) Attempts @ 1007, 1025, 1042, 1058, 1116 made 2 good attempts at erupting but again failed, 1133, 1150, 1210 erupted!

Pool would fill and try to erupt about every twenty minutes for the entirety of the time I was there, but no eruptions were observed. The try at 1327 looked really promising, but no go. There appears to be a fair amount of water flowing in from another source. |

Opening Weekend saw no eruptions of Constant Geyser. It cycles as it has in the past at regular intervals (less than 20 min) but does not erupt. Per the YVO graphs this change occurred on April 8, 2014. I did not know how to interpret the drastic change in the shape of the YVO graph until I was able to observe the cycles in person. Some of them look quite promising with good blurps and overflow, but no eruptions were seen during the time it was observed. |

09/04/1977 Complete Log entry:
Little Whirligig started to erupt at 1016 there was no water in the pool when the geyser first sprayed. It lasted about 8 minutes. Constant geyser erupted twice during L.W. eruption, the first eruption was small 4-5 ft. the second was very powerful up to 25’
After L.W. Big Whirligig erupted at 1025
The pool was at an extreme low level when it started. Splutter pot started eruptions in unison with higher bursts matching the higher bursts of all four geysers. |
