During this time there were 11 solo eruptions of South Grotto Fountain. Intervals were 7-14 minutes, reaching heights of 15' max. Grotto seemed ready to erupt throughout with pressure pool cycling every 10 minutes. Generally, SGF began eruptions following pressure pool drops and shut off before it rose. More info on this odd grotto incoming once my phone connects to the internet. |

GF pressure pool came up slowly. SGF started splashing but it didn't erupt. Earlier GF pressure pool was rising on every cycle and SGF was erupting each cycle. |

South Grotto Fountain was active having eruptions at intervals of 7 to 15 minutes starting sometime before 0700. The eruptions alternated with high water levels in Indicator Spring and boiling episodes in Grotto Fountain. |
