Filling but not in overflow yet at 1912. First audible trickles of overflow at 1923 (heard from roadside opposite boardwalk where I remained for most of sit). 1934 first visible wavy action in standing water around vent; little to no breeze. Insects waking up. Sizzle in pool at far edge from boardwalk 1938.1941 audible bubbling at edges despite LOTS of talking over at boardwalk benches.1954 nice roil up. 2006 frothy bubbles floating by in front of me as water starts to wet runoff area. 2014 Great Blue Heron flew over headed southish - none of the growing peanut gallery noticed. 2022 constant roiling on surface of pool for about 5 min now. 2032 meter boil! |

I believe GF is post-eruptive. At 1030 water level was about a foot below the rim. there was light boiling around the inside of the rim. The boiling stopped at 1100 and water dropped a few inches. |

Sat around G.F. From 12:20 to 15:50 the pool looked to be in recovery from the previous eruption, the pool had risen anywhere 6”-1’4’ from the time I sat, I assume that morning eruption was anywhere from 8:30 - 10:00. |
