5/21/2012 Guardian appeared to undergo an eruptive cycle of some kind. Approx. 1815, only a wisp of steam rose from the vent. About 15 minutes later, steam and spray was forcefully jetting ~ 10 feet into the air from the vent. {note to future researchers - logbook said Black Growler - there was lots confusion this year since Guardian was in a high powered steam phase and they thought it was Black Growler until later in the summer - mab} |

Sunday July 29 - no time noted - Guardian is unusually steamy today! The force of the steam has greatly increased since my last close observation of 3 weeks ago. Beautiful deposits of brown, gold, orange and black have increased around the vent. {entry also includes new geyser 45 ft north of Guardian mab} |

Guardian Geyser is a continuous spouter, has been for at least a year. What is noteworthy is its bronz[e] colored metallic sulfide deposit lining which extends out to the vents upper rim & is estimated to be at least a centimeter thick. |
