Smell of eggs |
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. |

Pool pretty darn low. Guessing it had a long series last night. It is possible it could have been a crash. But if it is, it's a very large crash. |
