This a response to Udo’s flag on the other geyser entry that I used to enter GF overflow: we cannot satellite text notes into GT if I could I would do it but unfortunately this is not the case currently , hopefully the capability to add notes can be added soon. |

In overflow at 0710. Based on strength of overflow, I believe it is a continuation of the overflow that started at 0615.

Overflow with low boiling until 1549 when pool boiled up 2-3 feet high. After 2-3 minutes of vigorous boiling, the pool level started bouncing in and out of overflow with boiling that looked like post-eruptive inside the crater rim boiling when the pool was below overflow. At 1609 the pool dropped several inches, ending the in-and-out of overflow activity. |
